- Ovarian Torsion: Diagnostic Features on CT and MRI With Pathologic Correlation
  OBJECTIVE. The CT and MRI features of ovarian torsion are illustrated with gross pathologic correlation. Ovarian enlargement with or without an underlying mass is the finding most frequently associated with torsion, but it is nonspecific. A twisted pedicle, although not often detected on imaging, is pathognomonic when seen. Subacute ovarian hemorrhage and ab […]
- Multidisciplinary Considerations in the Management of High-Risk Breast Lesions
  OBJECTIVE. The purpose of this review is to discuss the controversy and lack of consensus in the management of high-risk breast lesions, including flat epithelial atypia, atypical ductal hyperplasia, lobular neoplasia, radial scar, papillary lesions, and mucocelelike lesions, after diagnosis with core needle biopsy. CONCLUSION. A single uniform approach may […]
- Risk of Malignancy When Microscopic Radial Scars and Microscopic Papillomas Are Found at Percutaneous Biopsy
  OBJECTIVE. The objective of our study was to assess the incidence of associated malignancy when microscopic radial scars and microscopic intraductal papillomas are encountered at percutaneous biopsy for lesions that otherwise reveal benign histopathology. MATERIALS AND METHODS. A search of the pathology database for the period from December 14, 2006, through […]
- Subcutaneous Abdominal Wall Masses: Radiological Reasoning
  OBJECTIVE. A 36-year-old woman presented to her primary care physician with right lower abdominal pain. Her physician subsequently requested a CT to rule out appendicitis. Contrast-enhanced CT was performed and revealed no evidence of appendicitis but showed two subcutaneous ovoid soft-tissue masses anterior to the rectus sheath in the upper pelvis. Pelvic M […]
- Nonthrombotic Pulmonary Embolism
  OBJECTIVE. The purpose of this essay is to highlight the clinical features and imaging findings associated with different types of nonthrombotic pulmonary embolism. CONCLUSION. Nonthrombotic pulmonary embolism is an infrequent condition with various causes that can be life-threatening pathologic conditions. The entity presents a diagnostic challenge because […]
- A New MDCT Technique for the Detection and Anatomical Exploration of Urogenital Fistulas
  OBJECTIVE. We tested a new MDCT technical protocol, combining IV and intravesical positive contrast agent and intravaginal neutral contrast agent, that optimizes exploration of urogenital fistulas. We examined three patients (four CT examinations in total) with this technique and proved that a preexisting subtle ureterovaginal fistula that was under treatmen […]
- Chronologic Change in the Growth Plate After Radiofrequency-Induced Thermal Injury: MRI-Histologic Correlation
  OBJECTIVE. The purposes of this study were to assess chronologic changes in normal growth plate after radiofrequency-induced thermal injury and to evaluate the feasibility of MRI for revealing alteration of the growth plate. MATERIALS AND METHODS. Radiofrequency ablation was performed on the right proximal tibia of 13 8-week-old New Zealand White rabbits. An […]
- Meniscal Tear Configurations: Categorization With 3D Isotropic Turbo Spin-Echo MRI Compared With Conventional MRI at 3 T
  OBJECTIVE. The purpose of our study was to compare the accuracy of 3D fat-suppressed isotropic turbo spin-echo (TSE) sequences using sampling perfection with application-optimized contrasts using different flip angle evolution (SPACE) with 2D conventional MRI at 3 T in determining meniscal tear types. MATERIALS AND METHODS. Sixty-nine patients with arthrosco […]
