OPG & Lateral Cephalogram: A Closer Look

OPG & Lateral Cephalogram: A Closer Look
Comments Off on OPG & Lateral Cephalogram: A Closer Look

At Vision XRAY, we offer a wide variety of radiological services for patients. To diagnose and treat conditions, we use examinations that assess bones, muscles, organs, nerves, and more. We utilise equipment that can focus solely on the limbs, torso, head, and even on the teeth. In fact, dental imaging is a frequently used service here at Vision XRAY. At Vision XRAY we offer a full range of dental imaging services including CT cone beam, CT Dental scan, OPG, TMJ X-ray and Lateral Cephalogram. Two of our frequently used procedures for dental imaging include the OPG and the lateral Cephalogram. Today, we take a closer look at what these two examinations are all about.

OPG (Orthopantomogram)

An OPG can be an extremely useful diagnostic tool for dentists, oral surgeons, orthodontists, and other physicians who work with the teeth, mouth, and jaw. The OPG delivers a wide image of the patient’s jaw region on a single film. Essentially, this is a panoramic x-ray of the jaw and teeth which encompasses the front and sides.

Such a x-ray may be needed at various points in your life. If you’re experiencing jaw tension, popping, or frequent headaches, your practitioner may want to assess you for disfunction of the temporomandibular joint (TMJ). This condition causes many people to inadvertently grind their teeth and experience pain. Using the OPG, the radiologist and practitioner can note problems or misalignment with the joint. They may also be able to see evidence of teeth grinding.

The OPG is frequently used in patients of all ages, younger patients or those entering orthodontic services, older patients or those looking for tooth decay or prior to tooth implantation. The panoramic image is ideal for showcasing the position of the teeth, the relation to the sinus and nerve and for those teeth that have emerged to the surface and those that are still under the gum line. This can help your physician prepare and plan for the best mode of treatment. The OPG is also commonly used to determine whether wisdom teeth are present in a patient, and can assist in preparation for an extraction.

What to Expect With an OPG

An appointment for an OPG should not take more than 15-20 minutes. You will need to remove jewellery or metallic objects from head and neck. The patient stands near the machine and places their chin onto a chin rest. To steady your jaw, your radiographer will ask you to bite down on a small plastic portion. The x-ray mechanism of the OPG machine rotates around the jaw, creating the panoramic image. The patient will be asked to stand still while the images are obtained. The x-ray itself takes only takes seconds.

Lateral Cephalogram

Another useful assessment tool in dental imaging is the lateral cephalogram. This is an x-ray which generates a side view of the head that can provide important information about the teeth and jaw. The lateral cephalogram shows facial structure, bone, and soft tissue. Your radiologist or dental practitioner can use these images to study the relation of your teeth to your jaw, assess problems in alignment or growth patterns, and prepare treatment.

The lateral cephalogram is best for observing jaw alignment. If you have an overbite or underbite, for example, these images will provide better detail and allow your practitioner to develop the best approach for your needs. This x-ray is commonly used in children to predict growth patterns in the teeth and jaws. The lateral cephalogram is used with adults as well, to study changes made from treatment or track other issues.

If you are working with an orthodontist, the lateral cephalogram may be ordered alongside the OPG. This x-ray is useful in tracking the progress of treatment.

What to Expect With a Lateral Cephalogram

An appointment for a lateral ceph should take approximately 15-20 minutes. Often, you’ll receive this scan in conjunction with the OPG. You will need to remove jewellery and metallics from your head and neck. For your lateral ceph you’ll be asked to keep your teeth together, and may lean your forehead against a steadying implement. The x-ray itself will be completed in only a few seconds

Tips for Choosing a Great Radiologist

Tips for Choosing a Great Radiologist
Comments Off on Tips for Choosing a Great Radiologist

Selecting a medical professional can often be a challenge, and a process that can feel overwhelming. There’s a great deal of information out there, and a seemingly greater number of providers. While you put care into selecting a primary physician, it’s important to choose the right medical professionals in other areas. Radiology is no exception. But how do you find the right radiologist for you? How do you ensure you select a great radiologist?

Great Reputation

Perhaps the most important indicator of quality in the medical field comes from word-of-mouth recommendations. When individuals find an outstanding professional, they often want to share this news with others. You should look for a radiology practice that has a top reputation and is known for their consistent excellence in care and service. Find out what groups and centres are most celebrated in your area.

Training & Technology

Radiology is a specialised and highly-technical field. When seeking the right radiologist, you want a team that has extensive experience and training. Ideally, a centre should have a number of radiologists with superior credentials and who focus on a range of specialties. This lets you know you’re in capable hands and are working with a team who has experience in all aspects of the field.

It’s also wise to pick a radiology practice which uses only the highest quality of equipment and state-of-the-art technology. Teams that keep on top of the latest technological advances and emphasise low-dose radiology machinery also earn points in this category.

Communication & Collaboration

A radiologist may be top in their field, but this accomplishment is diminished if he or she lacks exceptional communication skills. It is imperative that your radiologist is equipped and ready to work closely with your primary or referring physician, when necessary. This level of collaboration ensures you receive the best possible medical care.

At Vision XRAY, we are in constant communication with physicians and other healthcare providers, and we utilise teleradiology technology for ease and swiftness of sharing medical records and increasing communication and cooperation.


While such factors may not be as important as quality of care, you should consider logistics when selecting a radiologist, such as convenience of the practice location. You will likely wish to work with a radiology centre that is in your area, particularly if you anticipate frequent visits. A radiology practice with several locations may be ideally suited to your needs.

Commitment to Patient Care

Above all, you owe it to yourself to choose a radiologist who demonstrates a sincere commitment to patient care. You want to be in the best hands when it comes to your health and safety.

At Vision XRAY, we believe we embody all of the above criteria, but most of all, we strive to emphasise our dedication to offering the utmost level of care for each and every patient. In everything we do, we aim to promote our core values of compassion, justice, human dignity, excellence, and unity. If you’re seeking a great radiologist, please consider Vision XRAY, and find out why we are the radiology group against which all others are measured.

Comments Off on What is Teleradiology?

You may have heard that Vision XRAY offers teleradiology services within our practice. Yet you may be left wondering: just what is teleradiology? Teleradiology is the sharing of radiological medical images such as x-rays, MRIs and CT scans via electronic technology. The purpose of this system is to allow patient information to be available remotely. This helps to achieve greater accuracy, efficiency, and speed when it comes to patient diagnosis and treatment. The ability to share imaging easily and quickly allows patients and radiologists access to other radiologists as well as specialists. It also facilitates simple communication between physician and radiologist. Working with our healthcare partners, we enable rapid image sharing with community medical centres, hospitals, and private health centres.

Teleradiology at Vision XRAY

At Vision XRAY we use the RRRA (Remote Radiology Reporting Australia) system of teleradiology. RRRA was the first teleradiology practice in Australia, founded in 2001 and expanding ever since. We have 8 certified teleradiologists at Vision, and they prepare and handle imagery from MRI, CT scans, ultrasound, cone beam CT, dental x-ray, and chiropractic x-ray, among others. In most cases, images are transmitted within a timeframe of 24 hours–faster during emergency or urgent circumstances.

Technologically speaking, the RRRA teleradiology system is very advanced. Information is shared via a secure PACS system using Wide Area Network (WAN) and broadband as well as wireless options. A VPN as well as other protective measures ensures security and confidentiality of transmitted data. The IT infrastructure is strong and expertly-managed; in the case of any outages or errors, the system is supported by multiple servers, data backups, and other fail-safe mechanisms to keep the program up and running. At Vision XRAY, our teleradiologists have dedicated workstations for sending and receiving imagery, equipped with state of the art technology.

Practical Applications and Benefits

Thirty or so years ago, technology necessitated that radiologists physically be present when their expertise was needed. Teleradiology has vastly altered the process for analysis and diagnostic of medical imaging; radiology remains at the forefront of ‘telemedicine’ or medical care provided remotely or across several locations. The use of teleradiology allows radiologists to communicate clearly and easily with hospitals, physicians, surgeons, and more. This has certainly changed radiology practices, allowing radiologists to work effectively in various locations and streamlining and improving the process for patients.

As a patient at Vision XRAY, we may use teleradiology as an effective tool in your diagnosis and treatment. Communication with doctors, hospitals, and radiologists is better facilitated through the use of this premier technology and you can feel confident that Vision XRAY is committed to continuing to use the best available technology and practices available.


Importance of Medical Imaging

Medical imaging is an extremely important element in medical practice in this day and age, but have you ever stopped to consider its true importance? Medical imaging has changed the face of the healthcare industry and allowed practitioners and scientists to learn more about the human body than ever before.

In diagnosing an ailment or illness, physicians frequently order diagnostic scans such as an xray, CT scan, or MRI. While medical knowledge and discernment forms the basis of health practitioner diagnoses and decisions, medical imaging is a vital part of confirming any diagnosis. Medical imaging can also assist in decisions regarding treatment and future care of the issue. As technology advances, medical imaging can inform the doctor of internal problems that a basic external examination would fail to detect. Medical imaging is absolutely necessary when tracking the progress of an ongoing illness. MRI’s and CT scans allow the physician to monitor the effectiveness of treatment and adjust protocols as necessary. The detailed information generated by medical imaging provides patients with better, more comprehensive care.

The use of ultrasound imaging is extremely important for expectant mothers. Ultrasound technology has advanced significantly over the past decade, and sonogram images are now produced with a much higher resolution, creating finely detailed images. This gives obstetricians a vastly improved picture of the baby’s health and progress in the womb, allowing them to ascertain any issues of concern much earlier on in the pregnancy. As well as obstetrics, ultrasound is extensively used on other parts of the body including the soft tissues of the neck, breasts, abdomen, pelvis, and soft tissues of the extremities. It is also used as a guide for biopsies of soft tissues and for some treatments.

One further benefit of medical imaging is its function in preventative care. Recommended evaluations such as mammography can help detect early signs of breast cancer. An increase in the use of mammograms has been suggested to account for a 30% decrease in breast cancer fatalities since 1990.

Medical imaging also is used by surgeons as an aid in surgical procedures. One example of medical imaging as an effective surgical tool is in the case of endoscopic sinus surgery. The extensive network of the sinus can be examined closely prior to the procedure through study of a CT scan. CT scans can provide 3D images of various cross-sections of the body–images which are of absolute necessity when preparing to operate on such an area. CT scans are also being utilised more frequently during surgical procedures, for a similar purpose of guiding physicians throughout a delicate internal operation.

Medical imaging is truly a vital element of the healthcare world–an essential tool for physicians to assist with diagnostics, treatment, and prevention. As technology continues to advance at a rapid rate, we will see growth in medical imaging technology as well. With scientific advancement and a continued effective use, medical imaging will continue to help with earlier detection of health issues, aid in easier treatment, and provide increased preventative care.
