To ensure accurate targeting and repeatability, 3D TRUS-guided biopsies require registration to determine coordinate transformations to (1) incorporate pre-procedure biopsy plans and (2) compensate for inter-session prostate motion and deformation between repeat biopsy sessions. We evaluated prostate surface- and image-based 3D-to-3D TRUS registration by measuring the TRE of manually marked, co...

background: to reduce uncertainties of patient positioning, the computerized tomography (ct) images acquired at the treatment planning time can be compared with those images obtained during radiation dose delivery. this can be followed during dose delivery procedure as image guided radiotherapy (igrt) to verify the prescribed radiation dose delivery to the target as well as to monitor radiation...

Endomyocardial biopsy is a commonly performed useful procedure utilized for the evaluation of cardiac tissue. Biopsy may be used to monitor transplant rejection, but it has many other applications including the evaluation of myocarditis, cardiomyopathy, chest pain, arrhythmia, and secondary involvement by systemic diseases. Drug toxicity may be evaluated and neoplasms may be biopsied. Recent de...

Abstract Image-guided core-needle breast and axillary biopsy (CNB) is the standard-of-care procedure for diagnosis of cancer. Although risks CNB are low, most common complications include bleeding hematoma formation. Post-procedural particular concern in patients taking antithrombotic therapy, but there currently no widely established standard protocol United States to guide therapy management....

Face transplantation is being performed with increasing frequency. Facial edema, fluid collections, and lymphadenopathy are common postoperative findings and may be due to various etiologies, some of which are particular to face transplantation. The purpose of this study was to demonstrate how postoperative imaging and image-guided minimally invasive procedures can assist in diagnosing and trea...

OBJECTIVE Image-guided prostate biopsy has become routine in medical diagnosis. Although it improves biopsy outcome, it mostly operates in 2 dimensions, therefore lacking presentation of information in the complete 3-dimensional (3D) space. Because prostatic carcinomas are nonuniformly distributed within the prostate gland, it is crucial to accurately guide the needles toward clinically importa...

Identifying the causative pathogens in patients with pyogenic vertebral osteomyelitis is important for optimizing antibiotic therapy. Thus, we examined patient characteristics and investigated the efficacy of the combined use of blood culture and image-guided biopsy culture for identifying the causative pathogens of pyogenic vertebral osteomyelitis. A case series study was conducted in hospital...

Received September 14, 2006. Accepted after revision January 9, 2007. demonstrated a markedly hypoechoic nodular image and posterior acoustic shadowing, with 2.0 cm in diameter (Figure 2). Initially, the patient was submitted to fine-needle aspiration biopsy that resulted inconclusive (smear presenting rare, nonatypical epithelial cells). Considering the unsatisfactory result, ultrasound-guided...

OBJECTIVES The aim of this study is to determine the utility of transrectal real-time elastography (TRTE)-guided prostate biopsies in patients subjected to transrectal ultrasound (TRUS)-guided transperineal prostate biopsies. MATERIALS AND METHODS A total of 108 consecutive patients suspicious for prostate cancer (PCa) with elevated serum prostate specific antigen (PSA) level > 4 μg/L or abno...
