Issues in Imaging Malignant Neoplasms of the Female Reproductive System
Fri, 28 Nov 2008 05:13:41 -0000
Publication year: 2009Source: Current Problems in Diagnostic Radiology, Volume 38, Issue 1, January-February 2009, Pages 1-16Nagaraj-Setty, Holalkere , Avinash M., Katur , Susanna I., LeeRadiological evaluation of malignant neoplasms of the female reproductive system is invaluable in the initial diagnosis, staging, treatment planning, and follow-up management. Radiologists serving as consultants for the general primary care internist, gynecologists, and specialists in gynecologic oncology should be familiar with the strengths and limitations of various modalities used to evaluate gynecologic cancer patients. This article discusses the most common female reproductive tract neoplasms (ie, cervical, endometrial, and ovarian cancers) and the role of ultrasound, computed tomography, magnetic resonance imaging, and positron emission tomography in their diagnosis and management. Imaging features that impact on clinical diagnostic or treatment algorithms...
Pharyngeal Dysphagia: What the Radiologist Needs to Know
Fri, 28 Nov 2008 05:13:41 -0000
Publication year: 2009Source: Current Problems in Diagnostic Radiology, Volume 38, Issue 1, January-February 2009, Pages 17-32Patrick D., Grant , Desiree E., Morgan , Francis J., Scholz , Cheri L., CanonDysphagia is defined as difficulty in swallowing. Oropharyngeal dysphagia is defined as difficulty in moving the bolus from the mouth to the esophagus. The best initial evaluation of suspected oropharyngeal dysphagia is a barium study which can evaluate motility of the oropharynx and hypopharynx and provide double-contrast views that may identify structural or mucosal abnormalities. Pharyngeal diverticula, Zenker's and Killian–Jamieson diverticula, and pharyngeal pouches are readily identified on these studies. Zenker's diverticula are the commonest diverticulum implicated in pharyngeal dysphagia and typically occur in the setting of cricopharyngeal dysfunction. The radiologist must not only diagnose these diverticula but also understand...
Vascular Closure Devices: A Comparative Overview

Radiologists performing arterial access procedures should be aware of when and how to use them, as well as the advantages and disadvantages of various devices, and any complications that may occur. This review intends to provide an overview of these devices, focusing on how they work, their efficacy in achieving hemostasis, any risks associated with their use, and our view as to which should be used for particular indications. There are three main categories of vascular closure devices: collagen based, suture based, and staples and clips. Newer generation devices...

Triple-Layer Appearance of Brodmann Area 4 at Thin-Section Double Inversion-Recovery MR Imaging.
Kim EY, Kim DH, Chang JH, Yoo E, Lee JW, Park HJ Related Articles Triple-Layer Appearance of Brodmann Area 4 at Thin-Section Double Inversion-Recovery MR Imaging. Radiology. 2008 Dec 19; Authors: Kim EY, Kim DH, Chang JH, Yoo E, Lee JW, Park HJ Purpose: To investigate whether thin-section axial double inversion-recovery (DIR) brain magnetic resonance (MR) imaging at 3.0 T can help distinguish the primary motor cortex (PMC), or Brodmann area 4, from other selected cortical regions, including the primary sensory cortex (PSC), or Brodmann areas 1-3, on the basis of the presence of a "triple-layer" appearance. Materials and Methods: This prospective study was approved by the institutional review board; informed consent was obtained from patients. This study included 191 patients (94 female, age range, 5-80 years; 97 male, age range, 5-76 years) with normal findings at 3.0-T MR imaging. The presence or absence of a triple-layer appearance within selected cortical regions on DIR images was graded independently by two neuroradiologists as definitely present (grade 2), probably present (grade 1), or definitely absent (grade 0). Ten additional patients with tumors underwent DIR imaging and intraoperative cortical mapping for further validation of the PMC. A myelin-stained brain specimen image in a patient not imaged with DIR was correlated with a representative set of DIR images. Results: A triple-layer appearance was found in the PMC bilaterally in 184 of 191 patients; grade 0 was assigned in only seven patients, who were all younger than 10 years. Grades were significantly lower in patients younger than 10 years than in others (P < .0001) but were not significantly different between older age groups (P > .0018). Interobserver agreement was excellent (weighted kappa = 0.843). The PMC determined on DIR images was confirmed with cortical mapping in all 10 patients with tumors. Triple-layer appearance was not present in the other cortical regions examined, including the PSC (P < .01). The triple-layer appearance on DIR images corresponded to the myelin band within the PMC present on the myelin-stained specimen image. Conclusion: A triple-layer appearance was found in the PMC at thin-section 3.0-T DIR imaging but not in other examined brain regions and therefore might be useful as an adjunct sign for identification of motor regions.

Acute Appendicitis in Young Children: Cost-effectiveness of US versus CT in Diagnosis--A Markov Decision Analytic Model.
Wan MJ, Krahn M, Ungar WJ, Caku E, Sung L, Medina LS, Doria AS Related Articles Acute Appendicitis in Young Children: Cost-effectiveness of US versus CT in Diagnosis--A Markov Decision Analytic Model. Radiology. 2008 Dec 19; Authors: Wan MJ, Krahn M, Ungar WJ, Caku E, Sung L, Medina LS, Doria AS Purpose: To compare the cost-effectiveness of different imaging strategies in the diagnosis of pediatric appendicitis by using a decision analytic model. Materials and Methods: Approval for this retrospective study based on literature review was not required by the institutional Research Ethics Board. A Markov decision model was constructed by using costs, utilities, and probabilities from the literature. The risk of radiation-induced cancer was modeled by using the Biological Effects of Ionizing Radiation VII report, which is based primarily on data from atomic bomb survivors. The three imaging strategies were ultrasonography (US), computed tomography (CT), and US followed by CT if the initial US study was negative. The model simulated the short-term and long-term outcomes of the patients, calculating the average quality-adjusted life span and health care costs. Results: For a single abdominal CT study in a 5-year-old child, the lifetime risk of radiation-induced cancer would be 26.1 per 100 000 in female and 20.4 per 100 000 in male patients. In the base-case analysis, US followed by CT was the most costly and most effective strategy, CT was the second-most costly and second-most effective strategy, and US was the least costly and least effective strategy. The incremental cost-effectiveness ratios (ICERs) of CT to US and of US followed by CT to US were both well below the societal willingness-to-pay threshold of $50 000 (in U.S. dollars). The ICER of US followed by CT to CT was less than $10 000 in both male and female patients. Conclusion: In a Markov-based decision model of pediatric appendicitis, the most cost-effective method of imaging pediatric appendicitis was to start with a US study and follow each negative US study with a CT examination.
