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.

Radiologists may be the first to suggest the diagnosis of CN and can facilitate prompt intervention and treatment if they are aware of the radiographic manifestations of CN and the signs of progression of disease. Radiologists should also become aware of the evolving treatment of the disease as focus is shifting toward early surgical intervention and limb salvage rather than amputation. Knowledge of preoperative assessment, the types of surgeries performed, and some of the encountered postoperative complications enable the radiologist to facilitate timely intervention by our surgical colleagues and be a valuable member of the management team.A Review of Charcot Neuroarthropathy of the Midfoot and Hindfoot: What Every Radiologist Needs to KnowCorrie M.

To maximize the identification of ultrasound and mammographic correlates to MRI-identified lesions, one must carefully review the initial MRI examination as well as be cognizant of breast normal anatomy and variations in breast position across imaging modalities. We review the steps required for planification and realization of a successful second-look evaluation. After a correlate has been found and percutaneous biopsy performed, we recommend obtaining a T1-weighted noncontrast MRI sequence to verify metallic marker placement at the site of biopsy. This step ensures correct correlation between imaging modalities, provides immediate feedback for the radiologist, and, in case of error, allows the patient to be immediately redirected to repeat biopsy, often under MRI guidance. In the case of correct correlation, short-term follow-up is recommended, as for other breast percutaneous interventional procedures. We propose a simple management algorithm following second-look targeted studies.Second-Look Targeted Studies After Breast Magnetic Resonance Imaging: Practical Tips to Improve Lesion IdentificationIsabelle Trop, Maude Labelle, Julie David, Marie-Hélène Mayrand, Lucie Lalonde10.1067/j.cpradiol.2009.07.006Current Problems in Diagnostic Radiology 39, 5 (2010)2010-09-01Current Problems in Diagnostic Radiology2010-09-01395S0363-0188(10)X0004-4Original Articles200211http://www.cpdrjournal.com/article/PIIS0363018809000607/abstract?rss=yesComputed tomographic (CT) scanning technology now employs up to 320 detector rows of 0.5-mm width and allows rapid acquisition of isotropic volume datasets over the entire body. Data from a single CT acquisition can be reconstructed into image series that would formerly have required multiple acquisitions. Small isotropic voxels permit scan parameters to be general while reconstruction algorithms remain specific to anatomy. While this results in more efficient operation in the Emergency Department, it necessitates new ways of displaying, interpreting, and archiving the information. Critical decisions include how much of the patient to scan and how to time contrast injections when imaging multiple organs. These choices must be made in light of dose considerations to the patient and the general population of patients. The technical basis of high-density CT scanning is discussed, including detector configurations and reconstruction techniques. Volumetric scanning in the Emergency Department can improve patient care but requires a change of technical habits.How Will You Need Me, How Will You Read Me, When I'm 64 (or More!)?: Volume Computed Tomographic Scanning and Information Overload in the Emergency DepartmentDavid P.

Common indications for spinal cord stimulation include chronic neuropathic and oncological pain, intractable angina, or chronic pain secondary to vascular disease. It is estimated that up to 4 million patients may be candidates for the therapy. Therefore, it is likely that an increasing number of patients will have spinal neurostimulation devices implanted over the coming years. Because radiography and computed tomography are the primary imaging modalities used to evaluate the proper positioning of these devices, radiologists should be familiar with their appearance. The purpose of this article is to discuss the types of neurostimulation devices currently being used and to demonstrate their respective imaging appearances.Spinal Cord Stimulation: The Types of Neurostimulation Devices Currently Being Used, and What Radiologists Need to Know When Evaluating Their Appearance on ImagingVivek Kalia, Cary Bizzell, Rick Obray, Jon Obray, Tim Lamer, John A.
