Overview

Description

Causes and clinical presentation of temporomandibular disorders provide the context for comparing available imaging methods. MRI assessment then covers normal anatomy, disc position and motion, internal derangement, osteoarthritis, inflammatory disease, less common conditions, and structured reporting.

Learning Objectives

Select an appropriate imaging technique and MRI protocol for temporomandibular joint symptoms.
Recognise normal joint anatomy, disc position, and patterns of internal derangement.
Identify degenerative, inflammatory, and less common temporomandibular abnormalities.

Astrid Schweitzer^M.D.

Kaast, Germany

Consultant radiologist at TMC

Astrid Schweitzer (German) graduated from medical school in Germany in 1994. During university she completed her research work for her doctorate thesis on hearing loss defending it in 1995. She is a board-certified specialist in diagnostic radiology. Her main interest is head and neck radiology, particularly temporal bones, temporomandibular joints and paranasal sinuses reporting and also dental radiology. Astrid is the lead for TMC's Paranasal Sinuses (PNS) Expert Group at TMC where a novel 'structured/standardized reporting-tool' for paranasal sinuses reporting was introduced in 2015. She teaches PNS anatomy and pathology to new TMJ radiologist, double-read reports and also establish and maintain the ever growing PNS image reference image library.
