Abstract

The authors report their experiences with 1243 laparoscopic splenic biopsies performed between 1968 and 1982 at the Laparoscopy Center of the Regional Hospital in Padua. We may conclude that: The risk of laparoscopic splenic biopsy in minimal and fears regarding its performance are unjustified. The diagnostic value of splenic biopsy is evident if a comparison is made, in the different groups, between the percentage and the accuracy of the diagnoses made with the single macroscopic and the histological examinations, respectively. As well as the staging and follow-up of malignant lymphomas, examination of the spleen in clinically suspected splenopathy is a new and interesting indication for laparoscopy, for it is now possible to take one or more biopsies.

Targeting difficult accessible breast lesions: MRI-guided needle localization using a freehand technique in a 3.0 T closed bore magnet.

PURPOSE: To report the accuracy of magnetic resonance imaging (MRI)-guided needle localization for diagnosis of MRI detected suspicious breast lesions located in difficult accessible regions of the breast, using the freehand method in a 3.0 T closed bore magnet. MATERIALS AND METHODS: In five patients with five MRI-only breast lesions underwent MRI-guided needle localization for histopathologic evaluation of the lesions. All interventional procedures were performed in a 3.0 T MRI system with the patient in prone position and by using a dedicated phased array breast coil. MRI-guided needle localizations were performed by using a freehand technique. In our study, the high-resolution scan allowed preprocedural localization of all lesions without use of contrast enhancement. In all cases contrast-enhanced MRI was performed after insertion of the wire to confirm the tip of the wire in direct contact with the enhancing lesion. RESULTS: Needle localizations were performed in five patients. Histopathologic evaluation of tissue after surgery excision biopsy revealed one lymph node, three invasive ductal carcinoma and one ductal carcinoma in situ. Lesion size varied from 6 to 30 mm. Mean duration time was 25 min. No complications occurred during the intervention method. In the patient with the benign lesion control MRI of the breast after 6 months confirmed lesion removal. CONCLUSIONS: MRI-guided needle localization by using a freehand technique in a 3.0 T closed bore magnet is a safe and accurate method for diagnosis of difficult accessible breast lesions only visible on MRI.
