Medial-sided Ankle Pain
Abnormalities of the medial ligaments and posterior tibial tendon can occur because of acute injury or chronic instability or malalignment. Medial ankle injuries may occur because of pronation or supination–external…
MR Imaging of the Pediatric Foot and Ankle
MR imaging is ideally suited for characterization of the soft tissue, cartilaginous, and osseous structures of the pediatric ankle. An understanding of the normal MR imaging appearance associated with the…
Aftermath of Ankle Inversion Injuries
Acute and chronic ankle inversion injuries are a common source of pain and a diagnostic challenge. Several studies have shown a variety of injury patterns after inversion injury both in…
Normal Variants
Accessory muscles around the ankle are commonly encountered as incidental findings on cross-sectional imaging. Mostly asymptomatic, accessory muscles sometimes mimic mass lesions. They have been implicated as the cause of…
Technical Considerations
There are many challenges involved in obtaining diagnostic MR images of the foot and ankle. The complex anatomy and morphology, with curved and angular structures localized to the periphery of…
Integration of PET/MR Hybrid Imaging into Radiation Therapy Treatment
Hybrid PET/MR imaging is in early development for treatment planning. This article briefly reviews research and clinical applications of PET/MR imaging in radiation oncology. With improvements in workflow, more specific…
Pediatric Applications of Hybrid PET/MR Imaging
Hybrid PET/MR imaging systems have recently become available for clinical practice. The simultaneous physiologic and anatomic imaging offers the potential to reduce radiation dose and other advantages for pediatric patients….
PET/MR Imaging of Multiple Myeloma
PET–magnetic resonance (MR) is a hybrid imaging modality that combines PET and MR. Evidence for this new modality is in the process of being developed, but both component modalities are…
Applications of PET/MR Imaging in Urogynecologic and Genitourinary Cancers
Positron emission tomograph (PET)-magnetic resonance (MR) is a new modality combining PET and MR. In gynecologic cancers it can be used for staging of cervical and endometrial cancer, planning of…
Cardiac Applications of PET/MR Imaging
Simultaneous acquisition PET/MR imaging combines the anatomic capabilities of cardiac MR imaging with quantitative capabilities of both PET and MR imaging. Cardiac PET/MR imaging has the potential not only to…
