Ultrasound is a less expensive and easily performed imaging modality that can be used to evaluate the TMJ. This is simple way to look for the presence of a joint effusion. Ultrasound is also used to evaluate cartilage as well as disk displacement with both open and closed mouth imaging. It is used for image-guided injections for both diagnostic and therapeutic purposes. Typically, a linear transducer of 8 MHz or higher is ideal. The patient should be lying supine with the transducer placed parallel to a line extending from the tragus of the ear to the lateral surface of the nose over the TMJ.

You might be anxious about having these tests performed, but diagnostic imaging scans are generally painless and non-invasive. Still, it can be helpful to get an understanding of how they each work and their common uses. Knowing the differences between x-rays, CT scans and MRI tests can help ease your mind when you know what to expect.
Abstract:Radiation therapy (RT) plays a significant role in the management of head and neck malignancies. This study aimed to review the clinical symptoms and various imaging findings of osteoradionecrosis (ORN) and provide a clinical perspective on the development of ORN. The retrospective cohort was composed of 57 sites in 54 patients who had a history of RT and suspected ORN and 48 sites in 45 patients who were confirmed to have ORN. Image analyses included computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET)/CT, bone scintigraphy, and single-photon emission CT (SPECT). The irradiated tissue was damaged by RT, and the extent of damage was correlated with clinical symptoms. The bone marrow showed sclerotic changes and the devitalized bone showed bone resorption after invasive stimulation. Chronic trismus and pathological fracture are considered severe conditions, typically occurring in the last stage of ORN. Furthermore, neurological symptoms were an important sign of tumor recurrence, since diagnostic imaging was difficult. The possible treatment options vary depending on the stage of ORN. We speculate that bone sclerosis reactions and bone resorption are sequential reactions that seem to be protective measures of the bone to radiation injury.Keywords: osteoradionecrosis; trismus; computed tomography; magnetic resonance imaging; positron emission tomography; single-photon emission computed tomography; diagnostic imaging
Oral and Maxillofacial Radiology: A Diagnostic Approach, Second Edition is a revised edition of this illustrated reference to the wide range of diagnostic imaging modalities available for investigating lesions affecting the face and jaws. Written by experts in various specialty areas, including medical radiologists, oral and maxillofacial radiologists, functional imaging specialists, and radiation oncologists, the book includes more than 450 clinical images demonstrating the concepts discussed, with more images covering cone beam computed tomography, positron emission tomography, and interventional procedures.
Accurate, convenient and fast diagnostic imaging is the starting point in diagnosing a range of medical conditions. Los Alamitos Medical Center and its affiliate diagnostic imaging locations offer innovative imaging options in a comfortable outpatient setting.
Certain tests may also involve exposure to small amounts of radiation, and may include the use of contrast agents to enhance the visualization of structures in the body. These are given orally or intravenously. Some of the most common types of diagnostic imaging tests include X-ray, CT scan, nuclear medicine scan, MRI scan, mammography and ultrasound.
When you come to us for diagnostic imaging, our team of dedicated and attentive radiology staff will guide you every step of the way, from the time you schedule an appointment to the actual screening.
** Several countries including Australia, Canada, South Africa, Norway, the Netherlands, the United Kingdom diagnostic imaging by physiotherapists is common practice. For decades, United States military physiotherapists have held privileges to directly refer for imaging studies. United States physical therapy program accreditation standards have specific criteria regarding diagnostic imagine. 2b1af7f3a8
