A Radiologist's Guide to Response Evaluation Criteria in Solid Tumors.

Response Evaluation Criteria in Solid Tumors (RECIST), including version 1.0 and 1.1, has been universally accepted as the standard response assessment criteria for conventional chemotherapies.

Imaging in gastric anisakiasis.

Gastrointestinal anisakiasis is an uncommon zoonotic parasitic infection caused by consumption of raw or undercooked seafood infected with nematodes of genus Anisakis. Given the non-specific clinical presentation of acute abdomen, nausea, and vomiting these patients are often subject to radiologic imaging. We present ultrasound and computed tomography imaging features in a case of gastric anisakiasis demonstrating characteristic features of diffuse gastric submucosal edema, perigastric stranding and trace ascites that helped to further elaborate the clinical history of uncooked fish consumption prompting timely endoscopic diagnosis and management.

Multimodality imaging of ovarian cystic lesions: Review with an imaging based algorithmic approach.

Ovarian cystic masses include a spectrum of benign, borderline and high grade malignant neoplasms. Imaging plays a crucial role in characterization and pretreatment planning of incidentally detected or suspected adnexal masses, as diagnosis of ovarian malignancy at an early stage is correlated with a better prognosis. Knowledge of differential diagnosis, imaging features, management trends and an algorithmic approach of such lesions is important for optimal clinical management.

Normal and variant abdominal anatomy on magnetic resonance imaging.

The diagnostic usefulness of abdominal magnetic resonance (MR) imaging lies in the improved contrast resolution and ability to qualify several tissue characteristics of a specific organ or lesion. Our institution uses organ-specific protocols to facilitate technical reproducibility and optimize scan duration. These protocols are discussed individually in this article when applicable, noting that many build on a basic protocol with slight variations.

Rudimentary third lower limb in association with spinal dysraphism: Two cases.

Spinal dysraphism is a common congenital anomaly with many associated variants. One of the rarest associated findings is a full grown or rudimentary third limb, collectively called Tripagus. We present two cases of spinal dysraphism with rudimentary third limb arising from the ilium.
