Current Problems in Diagnostic Radiology RSS feed: Current Issue. Current Problems in Diagnostic Radiology covers important and controversial topics in radiology. Each issue presents important viewpoints from leading radiologists. High-quality reproductions of radiographs, CT scans, MR images, and sonograms clearly depict what is being described in each article. Also included are valuable updates relevant to other areas of practice, such as medical-legal issues or archiving systems. With new multi-topic format and image-intensive style, Current Problems in Diagnostic Radiology offers an outstanding, time-saving investigation into current topics most relevant to radiologists.http://www.cpdrjournal.com/?rss=yesElsevier Inc.en © 2010 Mosby, Inc. All rights reserved.

The advent of multirow detector computed tomography offers new opportunities to address the challenge of imaging in the presence of metallic hardware. This pictorial essay highlights current strategies for reducing metallic hardware artifacts and presents some illustrative clinical cases.A Review of Factors That Affect Artifact From Metallic Hardware on Multi-Row Detector Computed TomographyMilliam L.

With the biological behaviors quite different from each other, they form a clinico-radio-pathologic spectrum worth remembering. We present a review of common and uncommon focal hepatic lesions containing fat (micro- and macroscopic) within them and emphasize the role of imaging in their diagnosis.Gamut of Focal Fatty Lesions in the Liver: Imaging Manifestations with Emphasis on Magnetic Resonance ImagingNajla Fasih, Alampady Krishna Prasad Shanbhogue, Seng Thipphavong, Venkateswar R.

However, the relevance of the findings on knee MRI to the patient's symptoms and clinical course may often be uncertain. This article discusses the clinical significance and natural history of several common findings on knee MRI examinations.Magnetic Resonance Imaging of the Knee: Clinical Significance of Common FindingsEugene Lin10.1067/j.cpradiol.2009.05.003Current Problems in Diagnostic Radiology 39, 4 (2010)2010-07-01Current Problems in Diagnostic Radiology2010-07-01394S0363-0188(10)X0003-2Original Articles152159http://www.cpdrjournal.com/article/PIIS0363018809000383/abstract?rss=yesMagnetic resonance imaging is the current imaging modality of choice in the evaluation of patients presenting with myelopathic symptoms in the search for spinal cord lesions. It is important for the radiologist to recognize and differentiate nonneoplastic from the neoplastic process of the spinal cord as the differentiation of the 2 entities is extremely crucial to the neurosurgeon. This article presents a broad spectrum of benign intramedullary spinal abnormalities including syrinx, contusion, abscess, infarction, myelitis, multiple sclerosis, sarcoid, cavernoma, and arteriovenous malformation. Rare intramedullary neoplasms including dermoid tumor, astrocytoma, ependymoma, hemangioblastoma, lymphoma, ganglioneuroblastoma, and metastases are also illustrated. The clinical presentation and magnetic resonance signal characteristics as well as the differential diagnosis of the intramedullary lesions are discussed. The potential pitfalls in the differentiation of tumors from nonneoplastic disease of the spinal cord are also elucidated.Magnetic Resonance Imaging of Intramedullary Spinal Cord Lesions: A Pictorial ReviewDaniel D.
