PURPOSE To quantify needle placement accuracy of magnetic resonance image (MRI)-guided core needle biopsy of the prostate. MATERIALS AND METHODS A total of 10 biopsies were performed with 18-gauge (G) core biopsy needle via a percutaneous transperineal approach. Needle placement error was assessed by comparing the coordinates of preplanned targets with the needle tip measured from the intrapr...

A general consensus on the role of testicular biopsy in non-obstructive azoospermia (NOA) is needed. This paper reviews and updates technical aspects and clinical performance of the percutaneous testicular biopsy techniques, in particular large-needle aspiration biopsy (LNAB), and proposes a flow chart for the management of NOA. The English literature and original data were reviewed or analyzed...

PURPOSE To examine the mammography and ultrasonography findings of patients who have a final histopathological diagnosis of sclerosing adenosis after breast biopsy, and to evaluate the follow-up results of patients who underwent core needle biopsies. MATERIALS AND METHODS Seventy-six of the 723 patients who underwent breast biopsy in our institution were diagnosed with sclerosing adenosis on ...

Needle core biopsy (NCB), as part of triple assessment for preoperative evaluation and diagnosis of breast cancer, is now considered as an established, highly accurate method for diagnosing breast cancer that has replaced either fine needle aspiration cytology or excisional biopsy as the initial diagnostic biopsy procedures in many institutions. In addition to its primary role in establishing a...

OBJECTIVE To assess retrospectively the accuracy of core needle biopsy in diagnosing papillary breast lesions and evaluate the prediction of malignant papillary lesions based on sonographic features. METHODS Review of 130 papillary lesions diagnosed on core needle biopsy (2002-2008) in 110 patients. The biopsy results were compared with final surgical pathology or evolution on imaging follow-...

BACKGROUND Malignancies located in the upper middle mediastinum usually do not have a sufficiently large acoustic window to permit a conventional ultrasound guided parasternal biopsy. This study was concerned with an alternative approach whereby ultrasound is applied through the supraclavicular paratracheal window to allow percutaneous biopsy of middle mediastinal malignancies. METHODS Fiftee...

BACKGROUND The quality of liver biopsy specimens obtained with different fine needle biopsy (FNB) techniques has not been compared. OBJECTIVES This study was performed to evaluate the diagnostic quality of three different liver FNB biopsy techniques. MATERIALS AND METHODS Two sequential biopsy series were performed on piglets. Three biopsy techniques were compared: capillary-FNB, core-FNB (...

BACKGROUND The histologic grade of a prostate needle-core biopsy specimen can determine whether a patient with prostate cancer is a candidate for radical prostatectomy or other treatment. Incorrect histologic grading can result in inappropriate treatment and possible liability. Thus, we conducted this study to determine the histologic-grading accuracy of prostate cancer needle-core biopsy speci...
