Avoiding Unnecessary Fine-Needle Aspiration Cytology By Accuractely Predicting The Benign Nature Of Thyroid Nodules Using Ultrasound, Sudhir Vinayak, Joyce Sande

Imaging & Diagnostic Radiology, East Africa

Objective: The objective of this study was to describe a reliable ultrasound based index scoring system based on ultraound characteristics to identify benign thyroid nodules and avoid unnecessary fine needle aspiration cytology.

Materials and Methods: Patients undergoing ultrasound-guided fine-needle aspiration cytology (FNAC) for thyroid nodules were evaluated prospectively. A total of 284 patients were evaluated from November 2005 to November 2011. There were 284 nodules. Any solid or partly solid focal nodule in the thyroid gland was included in the study. Cysts with no solid component were excluded. We used LOGIQ 9 (GE Healthcare) scanner equipped with a 10--14 MHz …

Dramatically Increased Musculoskeletal Ultrasound Utilization From 2000 To 2009, Especially By Podiatrists In Private Offices, Richard E. Sharpe, Levon N. Nazarian, Laurence Parker, Vijay Rao, David C. Levin

Department of Radiology Faculty Papers

PURPOSE: Over the past two decades, musculoskeletal (MSK) ultrasound has emerged as an effective means of diagnosing MSK pathologies. However, some insurance providers have expressed concern about increased MSK ultrasound utilization, possibly facilitated by the low cost and ready availability of ultrasound technology. The purpose of this study was to document trends in MSK ultrasound utilization from 2000 to 2009 within the Medicare population.

METHODS: Source data were obtained from the CMS Physician/Supplier Procedure Summary Master Files from 2000 to 2009, and records were extracted for procedures for extremity nonvascular ultrasound. We analyzed annual volume by provider type using specialties, …

Department of Radiology

Objective:To determine the diagnostic accuracy of liver ultrasound for the detection of hepatoma in chronic liver disease (CLD) Patients by either taking histopathology or serum alpha-fetoprotein levels or a biphasic computed tomography (CT) scan (whichever is available) as the gold standard. Study Design: Cross-sectional. Place And Duration Of Study: Radiology Department, The Aga Khan University Hospital, Karachi, Pakistan, from January 2007 to January 2010.

Methods:

A total of 239 Patients (156 males and 83 females) with clinical suspicion or surveillance of hepatoma in CLD referred to the radiology department for ultrasound evaluation followed by either liver biopsy and histopathology …

Neovascularity Patterns In Breast Carcinoma: Correlation Of Doppler Ultrasound Features With Sonographic Tumour Morphology, Riffat Shaheen, Saba Sohail, Kauser Jahan Siddiqui

Department of Radiology

Objective: To determine the association and correlation between morphologic features of breast cancer on gray scale ultrasound, and vascularity patterns and indices on color and spectral Doppler ultrasound.
Study design: Cross-sectional, analytical study.
Place and duration of study: Department of Radiology, Dow University of Health Sciences and Civil Hospital, Karachi, from August 2006 to June 2007.
Methodology: Fifty adult female patients with histopathological proven breast cancer underwent ultrasound for evaluation of morphologic features on gray scale mode; vascularity patterns on color Doppler scan and flow indices measurement on spectral Doppler ultrasound. Regression analysis was conducted to determine correlation between the …

Hemorrhagic Corpus Luteum Mimicking Heterotopic Pregnancy, Saba Sohail

Department of Radiology

Hemorrhagic corpus luteum (CL) is clinically known to simulate a number of medical, surgical and gynecologic conditions that cause acute abdomen. One such case is hereby presented that mimicked ectopic pregnancy clinically and heterotopic pregnancy on ultrasound. Laparoscopy was decisive.
