Urologists are often faced with the dilemma of managing patients with a negative initial prostate biopsy in whom clinical or pathological risk for prostate cancer still exists. Such real-life challenging scenarios might raise questions such as: Who should undergo further biopsies? What are the optimal predictors for prostate cancer on subsequent biopsies? What is the optimal biopsy protocol tha...

BACKGROUND AND PURPOSE CT-guided biopsy is the most commonly used method to obtain tissue for diagnosis in suspected cases of malignancy involving the spine. The purpose of this study was to demonstrate that a low-dose CT-guided spine biopsy protocol is as effective in tissue sampling as a regular-dose protocol, without adversely affecting procedural time or complication rates. MATERIALS AND ...

PURPOSE To assess the diagnostic value of an initial 24-sample transrectal ultrasound guided (TRUS) prostate biopsy protocol compared to the 10-core technique. MATERIALS AND METHODS We retrospectively reviewed the prostate biopsy database of consecutive men undergoing prostate biopsies under local anesthesia by using the 10 (Group A) and 24 (Group B) protocols. Men were stratified according t...

BACKGROUND As the choice of treatment in patients with cervical carcinoma depends on cancer stage at diagnosis, accurate staging is essential. PURPOSE To compare three different combinations of magnetic resonance (MR) sequences for preoperative staging. MATERIAL AND METHODS Fifty-seven consecutive patients with biopsy proven cervical carcinoma underwent MR imaging (MRI) staging followed by ...

results in the first series, cellularity and blood levels were significantly lower in capillary-fnb compared with cfnb (p < 0.001 and p = 0.011, respectively). there was no significant difference between cfnb and vacfnb in cellularity and blood (p = 0.15 and p = 0.1, respectively). in the second series, cellularity was significantly higher in cfnb compared with vacfnb (p < 0.001) with no signif...

The Working Group Uroradiology and Urogenital Diagnosis of the German Roentgen Society has developed uniform recommendations for the preparation and implementation of prostate MRI. In the first part detailed recommendations are given in tabular form regarding 1. anamnestic data before prostate MRI, 2. termination of examinations and preparation of examinations, 3. examination protocol and 4. MR...

background and objectives:breast cancer is the most common cancer among women worldwide. fine needle aspiration biopsy (fnab) is one of the methods of breast biopsy which is fast, easy and cost effective. the aim of this study was to evaluate the concordance rate between pathologic results of sonography or stereotaxy guided fnab and guided core needle biopsy (cnb) in the evaluation of breast le...

conclusion st-vab and mgl-eb are reliable biopsy methods for microcalcifications. in proper indications, breast microcalcifications could be obtained by each method without missing diagnosis of breast cancer. objectives to evaluate the outcome of st-vab and mammography-guided localization and excisional biopsy (mgl-eb) for microcalcifications. patients and methods two radiologists retrospective...

conclusion lesion depth from the pleural surface and the presence of emphysema were strongly correlated with the increasing incidence of pneumothorax after ct-guided pcnb. our results may be applicable for the risk management of pcnbs to reduce pneumothorax as a complication. background previous studies identifying risk factors for pneumothorax in percutaneous core needle lung biopsies reported...

Histological markers of chronic allograft nephropathy (CAN) in early protocol biopsies may ultimately result in deterioration of graft function. The aim of our study was to evaluate risk factors of early CAN histology and to determine whether treatment of borderline and subclinical acute rejections (BR/SAR) at 1-month posttransplant, prevents development and/or progression of CAN at 6-month bio...
