Transperineal and Transvaginal Sonography of Perianal Inflammatory Disease
Transperineal and Transvaginal Sonography of Perianal Inflammatory Disease http://www.ajronline.org/cgi/content/full/177/3/627 Lori K. Stewart ; Joan McGee ; Stephanie R. Wilson OBJECTIVE: Perianal infection arises in small intersphincteric anal glands predominantly located at the dentate line. Documentation of fluid collections and the relationship of inflammatory tracts to the sphincter mechanism is important for surgical treatment. Transanal sonography for […]
Simplified Approach to Umbilical Remnant
http://radiographics.rsna.org/content/11/1/59.full.pdf David J. DiSantis, MD ; Marilyn J. Siegel, MD ; Michael E. Katz, MD To facilitate an understanding of abnormalities related to the umbilical remnants, the authors present a simplified classification scheme on the basis of embryologic anatomic relationships. In a type 1 remnant, the entire duct (vitelline or urachus) is patent; in type […]
Multidetector CT Evaluation of Abdominal Trauma
http://www.radiologic.theclinics.com/article/PIIS0033838905001284/abstract Lisa A. Miller ; K. Shanmuganathan, MD Since the 1980s, CT has emerged as the imaging modality of choice to evaluate the hemodynamically stable patient with blunt trauma [1–3]. Many patients admitted to a trauma center have multisystem injuries sustained from high velocity trauma, most commonly a motor vehicle collision. As many as 68% […]
MR Evaluation of Acute Abdominal Pain in Pregnant Patients
http://www.appliedradiology.com/Article.aspx?id=13583 Gregory Wolfe, MD ; Aytekin Oto, MD The evaluation of abdominal pain in the pregnant patient is complicated by the physical changes in pregnancy as well as by the need to avoid fetal radiation exposure. While ultrasound is the preferred initial imaging study, some conditions require alternative imaging. This article presents a review of […]
Mesenteric Lymph Nodes Seen at Imaging: Causes and Significance
http://radiographics.rsna.org/content/25/2/351.full Brian C. Lucey ; Joshua W. Stuhlfaut ; Jorge A. Soto With the advent of multidetector computed tomography, routine evaluation of mesenteric lymph nodes is now possible. For the first time, normal mesenteric nodes may be reliably identified noninvasively. Because of the increasing volume of cross-sectional imaging examinations being performed, lymph nodes in the […]
Mesenteric Lymph Nodes- Detection and Significance on MDCT
http://www.ajronline.org/cgi/content/full/184/1/41 Brian C. Lucey ; Joshua W. Stuhlfaut ; Jorge A. Soto OBJECTIVE: Unsuspected mesenteric lymph nodes are frequently found on abdominal CT scans in everyday clinical practice. What to do with these findings has not been well established. The purpose of this study is to document the incidence of mesenteric lymph nodes in a previously […]
Mesenteric Adenitis: CT Diagnosis of Primary Versus Secondary Causes
http://www.ajronline.org/cgi/content/full/178/4/853 Michael Macari ; John Hines ; Emil Balthazar ; Alec Megibow OBJECTIVE: Our objective was to determine the clinical significance of mesenteric adentitis when detected on CT. MATERIALS AND METHODS: Mesenteric adenitis was considered present if a cluster of three or more lymph nodes measuring 5 mm or greater each was present in the right lower […]
MDCT of Patients with Acute Abdominal Pain
http://www.ajronline.org/cgi/content/full/183/4/899 Erik K. Paulson ; Tracy A. Jaffe ; John Thomas ; John P. Harris ; Rendon C. Nelson Numerous studies indicate that CT, when combined with careful physical examination and evaluation of laboratory results, provides useful diagnostic information in patients with an acute abdomen [1–4]. As a result, CT is increasingly used in the […]
Internal Hernia: Clinical and Imaging Findings in 17 Patients
http://radiology.rsna.org/content/218/1/68.full Arye Blachar, MD ; Michael P. Federle, MD ; S. Forrest Dodson, MD PURPOSE: To review the clinical and radiologic features of internal hernia and to derive useful radiographic and CT criteria to assist in diagnosis. MATERIALS AND METHODS: Retrospective review of medical records revealed 17 patients with surgically proved internal hernia (three paraduodenal, 14 transmesenteric) […]
