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...

A methodology is presented for constructing a statistical atlas of spatial distribution of prostate cancer from a large patient cohort, and it is used for optimizing needle biopsy. An adaptive-focus deformable model is used for the spatial normalization and registration of 100 prostate histological samples, which were provided by the Center for Prostate Disease Research of the US Department of ...

INTRODUCTION The aim was to examine the effect of a sedative or analgesic supplement to periprostatic nerve blockage (PNB) on pain reduction during probe insertion and needle penetration in patients undergoing transrectal ultrasound (TRUS)-guided prostate biopsy. We also investigated the effects of this procedure on the positive response rate in re-biopsy. MATERIAL AND METHODS One hundred TRU...

Adenosquamous carcinoma (ASC) and sarcomatoid carcinoma (SC) of the prostate are rare, but highly aggressive tumors. The occurrence of mixed carcinomas in the prostate is even more rarely reported. The present study reports the case of a 62-year-old male who was diagnosed with prostatic adenocarcinoma accompanied by multiple bone metastases, as shown by a needle biopsy and skeletal computed tom...

INTRODUCTION One of the most common procedures employed in modern clinical practice is percutaneous needle insertion [1]. This procedure encompasses surgical operations such as prostate biopsy and brachytherapy where the accuracy of the needle placement is important. In order to correctly estimate needle tip location, physicians currently rely on their knowledge of anatomical landmarks, and on ...

Arguably the most important step in the prognosis of prostate cancer is early diagnosis. More than 1 million transrectal ultrasound (TRUS)-guided prostate needle biopsies are performed annually in the United States, resulting in the detection of 200,000 new cases per year. Unfortunately, the urologist's ability to diagnose prostate cancer has not kept pace with therapeutic advances; currently, ...

BACKGROUND The only available method to detect prostate cancer is prostate biopsy; however, to our knowledge, no evidence-based clinical practice guidelines have been established on this topic. MATERIALS AND METHODS A three-year project was elaborated in which experts in the field worked to define the controversies existing in clinical practice regarding prostatic biopsies and then to develop...

Improved methods for prostate guided-biopsy are required to effectively guide needle biopsy to the suspected site. In addition, tissue stiffness measurement would help identifying a suspected site to perform biopsy because stiffness has been shown to correlate with pathology. More importantly, early detection of prostate cancer may guide therapy and eliminate invasive procedures. Vibro-acoustog...

In the recent years, prostate cancer was the most commonly diagnosed cancer in men. Currently secure diagnosis confirmation is done by a transrectal biopsy and following histopathological examination. Conventional transrectal biopsy success rates are rather low with ca. 30% detection upon the first and ca 20% after re-biopsy. The paper presents a novel system for stereotactic navigated prostate...
