Abstract

BACKGROUND: Traditional and disposable liver biopsy needles are expensive and add to economic burden in developing countries where the prevalence of liver disease requiring liver biopsy is high. AIM: To compare the technique of suction aspiration using a disposable syringe and an ordinary 40 mm long 18 gauge needle (internal diameter 1.27 mm), with Vim-Silverman's needle in obtaining liver tissue in patients with liver disease of various etiology. METHODS: Liver biopsy was performed in 60 patients each using either technique. The size of the biopsy tissue obtained and the number of times a diagnosis was reached with the two techniques were compared. RESULTS: The mean size of tissue obtained by suction aspiration (11.2 mm) was greater than that by the Vim-Silverman technique (6.3 mm) (p = 0.001). The tissue sample was inadequate for opinion in 3 patients in the aspiration group and in 10 patients in the Vim-Silverman group (p = ns). CONCLUSION: Suction aspiration liver biopsy can be done satisfactorily using disposable syringe and 18 gauge needle.

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.
