Diagnostic image-guided needle biopsy plays a vital role in the work-up and treatment of patients with extremity bone tumors. The radiologist and the orthopedic oncologic surgeon should take a team approach to this procedure, especially when the bone lesion might be a primary sarcoma for which limb-sparing surgery (LSS) would be considered. A set of anatomically based guidelines were developed ...

Patients 101 eligible patients (age range 20 to 95 y) from a group of 338 consecutive patients with suspected DVT who had routine venography. Patients with a positive result on venography and a subset of 25% of patients with a negative result, selected according to a predetermined sequence, were included. Exclusion criteria were pregnancy, known contrast allergy, renal failure, no leg symptoms,...

UNLABELLED The power of interpretation in the analysis of cranial computed tomography (CCT) among neurosurgeons and radiologists has rarely been studied. This study aimed to assess the rate of agreement in the interpretation of CCTs between neurosurgeons and a radiologist in an emergency department. METHOD 227 CCT were independently analyzed by two neurosurgeons (NS1 and NS2) and a radiologis...

Diagnostic reports. A radiologist at a PACS workstation needs ready access to prior reports. In most situations, reports are initially pushed to the RIS by the SR application, usually via an HL7 interface. If prior reports are stored in the RIS, how can they be available when a radiologist needs to look at them, for example, when reviewing a follow-up exam? T Most RIS systems cannot be queried ...

BACKGROUND There are a growing number of thyroid ultrasound courses to train endocrinologists, pathologists, and surgeons to perform ultrasound-guided fine-needle aspiration (FNA). However, there are limited data to support the efficacy of ultrasound-guided FNA performed by nonradiologists. METHODS We compared the efficacy of ultrasound-guided FNA performed by surgeons newly trained in thyroi...

OBJECTIVE The purpose of this article is to familiarize the radiologist with radiation dose in cardiac CT imaging and explain the current methods for dose reduction. CONCLUSION Advances in CT technology have resulted in a significant increase in cardiac CT applications. It is imperative that the radiologist understand the resulting dose implication to the patient and actively engage in optima...

We present a new variational-based method for automatic liver vessels segmentation from abdominal CTA images. The segmentation task is formulated as a functional minimization problem within a variational framework. We introduce a new functional that incorporates both geometrical vesselness measure and vessels surface properties. The functional describes the distance between the desired segmenta...

1475 phy, most likely due to contamination of the contrast medium or spinal needle used for the myelography. The plaintiff’s expert asserted that the fault lay with the radiologist or technologists under his supervision at the time. The expert witness retained by the defense, in his deposition, disagreed that the defendant–radiologist was responsible for the complication that arose from the mye...
