Elastofibroma dorsi: typical radiological features.

Elastofibroma dorsi is a rare benign and slow-growing fibro-proliferative lesion. It has a characteristic location (periscapular region) and a specific imaging appearance (sonography, CT, MRI) allowing accurate prospective diagnosis. The recognition of this benign lesion avoids unnecessary biopsy and/or surgery.

Detection of colonic masses with MR colonography.

Background/aims: Magnetic resonance colonography based on magnetic resonance imaging is a relatively new diagnostic modality for diagnosing colon pathology. The aim of this study was to evaluate its performance in detecting colorectal masses.

Methods: Thirty-three patients (20 male, 13 female; age range 28-85 years; mean age 78.

Characterization of focal liver lesions: use of mangafodipir trisodium (MnDPDP)-enhanced MR images.

Background/aims: We evaluated the characterization and detection of liver lesions using mangafodipir trisodium.

Methods: A total of 51 patients with liver lesions [13 hepatocellular carcinomas, 18 metastases, 14 hemangiomas, three cholangiocellular carcinomas, two hydatic cysts, and one focal nodular hyperplasia (FNH)] were examined by unenhanced and mangafodipir trisodium-enhanced MRI.

Results: After administration of mangafodipir trisodium by slow intravenous infusion, mangafodipir trisodium-enhanced MRI was performed at 15-30 min and 24 h.

Experimental evaluation of the effects of zoledronic acid on regenerate bone formation and osteoporosis in mandibular distraction osteogenesis.

Purpose: The aim of this study was to evaluate the effects of systemically administered zoledronic acid (ZA) on the bone mineral density (BMD) and bone mineral content (BMC) at mandibular distraction sites in rabbits.

Materials And Methods: Eighteen New Zealand white rabbits were randomly divided into 2 groups. Bone lengthening was performed in the left portion of the mandible through distraction osteogenesis at a rate of 0.

Three-dimensional MR and axial CT colonography versus conventional colonoscopy for detection of colon pathologies.

Aim: To evaluate the sensitivity and specificity of MR colonography (MRC) and CT performance in detecting colon lesions, and to compare their sensitivity and specificity with that of conventional colonoscopy.

Methods: Forty-two patients suspected of having colonic lesions, because of rectal bleeding, positive fecal occult blood test results or altered bowel habits, underwent the examinations. After insertion of a rectal tube, the colon was filled with 1000-1500 mL of a mixture of 9 g/L NaCl solution, 15-20 mL of 0.
