OBJECTIVE Sarcomas are rare mesenchymal malignancies. Accurate preoperative diagnosis is a prerequisite in considering investigational or institutional management algorithms that include neoadjuvant treatment. We reviewed our experience using core needle biopsy for chest wall sarcomas. METHODS A retrospective review of our sarcoma databases revealed that 40 core needle biopsies and 35 tumor r...

Percutaneous image-guided biopsies of pancreatic malignancies may prove challenging and nondiagnostic due to a variety of anatomic considerations. For patients with complex post-surgical anatomy, such as a Roux-en-Y gastric bypass, diagnosis via endoscopic ultrasound with fine-needle aspiration may not be possible because of an inability to reach the proximal duodenum. This report describes the...

BACKGROUND With the introduction of stereotactic surgery in humans by Spiegel and Wycis in 1947 and the great advances in neuroimaging, image-guided stereotactic brain biopsy is the mainstay for diagnosis of intrinsic deep-seated brain lesions. Stereotactic biopsy is usually safe, and the reported rate of complications is minimal, with mortality being reported in less than 1% and significant mo...

BACKGROUND Abdominal lymphadenopathy (AL) - a common clinical scenario faced by clinicians - often poses a diagnostic challenge. In the absence of palpable peripheral nodes, tissue has to be obtained from the abdominal nodes by image-guided biopsy or surgery. In this context a laparoscopic biopsy avoids the morbidity of a laparotomy. AIM This retrospective analysis of prospectively collected ...

In 2016, it is estimated 180,890 men are newly diagnosed with prostate cancer and 3,306,760 men live with prostate cancer in the United States. The introduction of multiparametric (mp) magnetic resonance imaging (MRI) of the prostate, standardised interpretation guidelines such as Prostate Imaging Reporting and Data System (PI-RADS version 2), and MRI-based targeted biopsy has improved detectio...

background infection after transrectal ultrasound (trus) guided biopsy of the prostate is a major and potentially life-threatening problem. using antibiotic premedication can not completely eliminate infection after biopsy. objectives we performed this study to determine the value of using povidone-iodine in prevention of post biopsy infection. patients and methods totally, 280 patients who wer...

Prostate biopsy and needle-directed prostate therapies are currently performed free-handed or with needle external templates under ultrasound guidance. Direct image-guided intervention robots are modern instruments that have the potential to substantially enhance these procedures. These may increase the accuracy and repeatability with which needles are placed in the gland. The authors' group ha...
