Normal ureter size on unenhanced helical CT.
OBJECTIVE Unenhanced helical CT is the imaging method of choice when evaluating patients with acute flank pain and suspected ureterolithiasis. In addition to directly identifying stones in the lumen of the ureter, CT secondary signs of obstruction such as ureteral dilatation are frequently present and can be helpful in establishing a diagnosis. The purposes of this study were to define ureteral...
متن کاملCT features of early pheochromocytoma.
A 53-year-old woman was found to have a left-sided peritoneal mass by CT during follow-up of a gallbladder polyp at the Gastrointestinal Department of our hospital. Unenhanced CT showed a round mass that was 2.0 cm in diameter with a well-defined margin. The lesion was homogenous with a comparatively high CT value (30 HU) (Picture 1). On enhanced CT, the mass showed homogenous enhancement (85 H...
متن کاملDetection of chordoma recurrence by F-18 FDG-PET/CT
Background: Despite the relative success of surgical resection followed by proton, proton/photon, or conventional radiotherapy in terms of recurrence-free survival, chordomas are still associated with a high rate of recurrence. To our knowledge there are only very few reported cases of this rare tumor detected by F-18 FDG-PET. Materials and Methods: In this case we show the significanc...
متن کاملDetection of brain metastases: comparison of contrast-enhanced MR with unenhanced MR and enhanced CT.
Contrast-enhanced MR studies were compared with noncontrast MR and contrast-enhanced CT scans in the evaluation of intraparenchymal brain metastases. Fifty consecutive inpatients were studied with short and long repetition time (TR) sequences before and after the administration of gadopentetate dimeglumine. In addition, a delayed short TR sequence was performed. The contrast CT, noncontrast MR,...
متن کاملMimics of renal colic: alternative diagnoses at unenhanced helical CT.
During the past decade, unenhanced computed tomography (CT) has become the standard of reference in the detection of urinary calculi owing to its high sensitivity (>95%) and specificity (>98%) in this setting. Numerous diseases may manifest as acute flank pain and mimic urolithiasis. Up to one-third of unenhanced CT examinations performed because of flank pain may reveal unsuspected findings un...
