To determine the optimal imaging modality for diagnosis and staging of ovarian cancer.Two hundred eighty women suspected to have cancer were enrolled in a prospective study before surgery. Doppler ultrasonography (US), computed tomography (CT), magnetic resonance (MR) used evaluate mass; conventional US, CT, MR stage spread.All three modalities had high accuracy (0.91) overall malignancy. In ovaries, was higher than that CT significantly US (0.78). extraovarian pelvis abdomen, similar...
To determine the ability of transrectal ultrasound to detect early localized prostate cancer, unsuspected (nonpalpable) cancer in contralateral lobe patients undergoing radical prostatectomy for clinically disease was evaluated. A total 59 with palpable confined 1 underwent before and step-sectioning specimen. Transrectal performed 5 or 7 MHz. real-time units. Pathological findings these cases revealed no tumor 34 (58%) presence 25 (42%). detected 13 cancers a sensitivity 52%. Of lesion...
PURPOSE: To determine the role, accuracy, and selection criteria of ultrasonographic (US) guidance for biopsy thoracic lesions. MATERIALS AND METHODS: Imaging-guided biopsies (n = 86) were performed in 84 consecutive patients. US was used lesions abutting chest wall; computed tomographic (CT) all masses surrounded by aerated lung. Mass location size, modality, histologic results, procedure time, complications recorded. RESULTS: Thirty-four (19 parenchymal, six pleural, wall, three...
A total of 135 symptomatic women with 262 breast implants were examined magnetic resonance (MR) imaging performed a body coil, ultrasound (US), or both to determine features implant rupture. Surgical proof was available for 33 62 implants; 24 ruptured and 38 intact. Complicated internal structure the most reliable predictor rupture: Diffuse low-level echoes seen on sonograms in 56% membranes (which correspond collapsed shell) MR images 58% implants. Fluid droplets within silicone 26% images....
Primary pancreatic lymphomas (PPL) are extremely rare. Clinically, PPL usually present with symptoms of carcinoma the head. An accurate cytopathologic diagnosis by fine-needle aspiration (FNA) is imperative because primary treatment nonsurgical, based on a combination chemotherapy and radiation therapy.Eight cases were identified from pathology files The Johns Hopkins Hospital over 14-year period (1989-2003). All diagnosed FNA performed under radiologic guidance. Needle rinses used to...

Ultrasound has become the initial approach to evaluating thyroid nodules, facilitating distinction between benign and malignant nodules based on composition, echogenicity, nodule border or margin, shape, presence of calcifications, dimensions. The American College Radiology (ACR) recommended Thyroid Imaging Reporting Data System (TI-RADS) as a classification system standardize ultrasound reports predict probability malignancy in using scoring (TR1-TR5) multiple characteristics size....
695 etastases to the pancreas are rare, being found at autopsy in 3–12% of patients with advanced malignancy [1, 2]. Recent reports have documented value CT both showing presence pancreatic metastases and providing guidance obtain a definitive tissue diagnosis [1–7]. Several these emphasized pivotal role radiologist first detecting mass then suggesting metastasis as likely diagnosis. This pictorial essay will review clinical features natural history illustrate its varied appearance on...
A correlative sonographic and histopathologic analysis was performed in 35 postmenopausal women with greater than 5-mm thickening of the endometrium at pelvic sonography. Women undergoing estrogen replacement were excluded from study. Four distinct patterns encountered. Pattern 1 consisted echogenic small cysts (endometrial polyp cystic hyperplasia [n = 9], atrophic cystically dilated glands 5], 3] microscopic examination). 2 homogeneous (proliferative adenomyomatous 1]). 3 irregular,...
The appearance of free silicone at mammography, ultrasonography (US), and magnetic resonance (MR) imaging is variable. classic dense areas opacity on mammograms, a highly echogenic pattern with or without hypoechoic masses US images, foci low signal intensity fat-suppressed T1-weighted MR images high water-suppressed T2-weighted images. Mammography reliable, cost-effective, readily available means demonstrating silicone. major disadvantage that its accuracy depends the capability operator to...
PURPOSE: To use radiologic-histopathologic correlation in an animal model to distinguish normal postoperative findings from evidence of residual tumor after cryoablation malignant hepatic tumors. MATERIALS AND METHODS: Hepatic was performed 12 rabbits with VX2 tumors and two healthy rabbits. Nonenhanced dynamic contrast material–enhanced computed tomography (CT) magnetic resonance (MR) imaging power color Doppler flow ultrasonography (US) were 7–8 days cryoablation. Histopathologic...
Abstract The parapharyngeal space (PPS) is a well‐defined anatomic zone of loose connective tissue lying deep to the tonsil and lateral pharynx. Neoplasms arising within PPS are rare. We retrospectively reviewed 24 fine‐needle aspirations (FNAs) performed at Johns Hopkins Hospital over past 16 years (1987–2002). Patients presented with neck pain, dysphagia, and/or intraoral swelling varying duration. Radiographic imaging disclosed masses, in size from 2.5 8 cm. most common...
Abstract Background The aim of this study was to review our experience with reoperative thyroid bed surgery (RTBS) for recurrent/persistent papillary cancer (PTC), and present an algorithm safe effective RTBS. Methods This is a retrospective study. Records 33 consecutive patients who underwent RTBS PTC in previously operated bed, were upon by the senior author (R.P.T.) July 2001 January 2006 reviewed. Reports pre‐ post‐RTBS serum thyroglobulin (TG) levels, high‐resolution ultrasound...
OBJECTIVE. The objective of this article is to assess radiologist concordance in characterizing thyroid nodules using the American College Radiology Thyroid Imaging Reporting and Data System (TI-RADS), focusing on effect experience reader concordance. MATERIALS AND METHODS. Three experienced three less radiologists assessed 150 TI-RADS lexicon. Percent was determined for various endpoints. RESULTS. Interreader five categories 87.2% shape, 81.2% composition, 76.1% echogenicity, 72.9% margins,...
