In detecting colon lesions, MRC achieved a diagnostic accuracy similar to CC. However, MRC is minimally invasive, with no need for sedation or analgesics during investigation. There is a lower percentage of perforation risk, and all colon segments can be evaluated due to multi-sectional imaging availability; intramural, extra-intestinal components of colonic lesions, metastasis and any additional lesions can be evaluated easily. MRC and CT colonography are new radiological techniques that promise to be highly sensitive in the detection of colorectal mass and inflammatory bowel lesions.

Background: Radiofrequency (RF) energy has been used for ablation and resection of liver tumors. Purpose: To present a new technique for the treatment of liver hydatid cyst disease. Material and Methods: Two patients with liver hydatid disease treated with RF energy cauterization and surgical resection are presented. Cystectomy was performed in a female patient aged 35 years and pericystectomy was carried out in another female patient aged 55 years using RF energy cauterization. Blood was not needed during the operation. RITA^® System (RITA Model 1500 RF Generator, RITA Medical Systems, Inc., USA) was used during the procedure. Conclusion: Cystectomy and pericystectomy in liver hydatid disease can be successfully performed with the assistance of RF energy.

MRI can show localization of the connection in this anomaly and helps the surgeon perform the operation with a limited incision. The operation time is therefore shorter and wound scarring less prominent.

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. We report two cases of bilateral elastofibroma dorsi illustrating characteristic imaging features on ultrasound, CT and MRI.
