BACKGROUND AND PURPOSE MSA-P and IPD have similar clinical presentations that may complicate accurate clinical diagnosis. Different iron-deposition patterns of those 2 diseases have been demonstrated in histopathology. The aim was to demonstrate the different iron-deposition patterns of MSA-P and IPD by using SWI phase images. MATERIALS AND METHODS(More)
BACKGROUND Idiopathic intracranial hypertension (IIH) is a clinical disorder of unknown etiology manifesting with increased intracranial pressure in the absence of hydrocephalus, an underlying mass lesion, and demonstrating normal cerebrospinal fluid composition. IIH may exhibit several non-specific imaging findings including: an empty sella, posterior(More)
Extrinsic venous compression is caused by compression of the veins in tight anatomic spaces by adjacent structures, and is seen in a number of locations. Venous compression syndromes, including Paget-Schroetter syndrome, Nutcracker syndrome, May-Thurner syndrome and popliteal venous compression will be discussed. These syndromes are usually seen in young,(More)
BACKGROUND Image-guided percutaneous thermal ablation is a commonly performed therapeutic procedure for various tumors. Thermal ablation is not frequently used in the pelvis as a result of anatomic concerns and the potential risk of nontarget tissue injury. TECHNIQUE Percutaneous thermal ablation is a minimally invasive procedure involving special probes(More)
A retrospective analysis of patients who underwent radiofrequency ablation (RFA) of intrahepatic cholangiocarcinoma (IHCC) was performed. Seven patients with 9 tumors underwent RFA. The mean tumor size was 2.4 cm (range=1.3-3.3 cm). RFA achieved technique effectiveness and local tumor control in 89% (8/9 tumors) of the patients respectively, with a mean(More)
To evaluate the indications, technique, results, and complications of image-guided percutaneous biopsy of the urinary bladder. This retrospective study included 15 patients (10 male, 5 female) who underwent image-guided percutaneous biopsy of the urinary bladder between January 1999 and December 2013. The medical records, imaging studies, procedural(More)
Lithium salts are the mainstay of treatment of bipolar disorder. However, the therapeutic index of lithium is narrow, and severe side effects may be seen. Nephrotoxicity is the most important side effect, which may progress to chronic renal failure. In this pictorial essay, we present ultrasonography, computed tomography, and magnetic resonance imaging(More)
A retrospective institutional-review-board-approved study was performed evaluating positron emission tomography (PET)-computed tomography (CT) imaging findings of peritoneal and omental involvement of lymphoma. Twelve patients were identified with a wide spectrum of imaging findings on PET-CT including but not limited to peritoneal thickening, ascites, and(More)
OBJECTIVE This study aimed to investigate the utility of three-dimensional reconstructions of paranasal sinus computed tomography data in depicting the anatomy of the frontal sinus drainage pathway. METHODS Twenty-nine patients underwent imaging of the sinuses for various clinical indications. Variations in frontal sinus recess anatomy were determined(More)
