Diffuse glial tumors with bithalamic involvement are rare in children. Diagnostic assessment can be difficult as the radiological findings can be unspecific.In order to enhance the diagnostic yield metabolic imaging with MRS and PET using FET ( O-(2-[(18)F]fluoroethyl)- L-tyrosine) was performed in two children (2 and 10 years of age). Co-registere...
Techniques in vascular and interventional radiology
Image-guided biopsy is a safe and well-established technique that is familiar to most interventional radiologists. Improvements in image guidance, biopsy tools, and biopsy techniques now routinely allow for safe biopsy of renal and adrenal lesions that traditionally were considered difficult to reach or technically challenging. Image-guided biopsy ...
Prostate cancer imaging : image analysis and image-guided interventions : international workshop held in conjunction with MICCAI 2011, Toronto, Canada, September 22, 2011 : proceedings
Prostate cancer affects 1 in 6 men in the USA. Systematic transrectal ultrasound (TRUS)-guided biopsy is the standard method for a definitive diagnosis of prostate cancer. However, this "blind" biopsy approach can miss at least 20% of prostate cancers. In this study, we are developing a PET/CT directed, 3D ultrasound image-guided biopsy system for ...

The management and treatment of an adolescent presenting with a fibroadenoma or virginal breast hypertrophy can be challenging as there is a paucity of original research on these conditions. Although surgical therapies are often discussed as first-line therapy in adolescents presenting with a breast mass, it is prudent that nonsurgical intervention...

PURPOSE. To compare computed tomography (CT)- guided core needle biopsy (CNB) with incisional biopsy in diagnosing musculoskeletal lesions. METHODS. 62 men and 50 women aged 12 to 83 (mean, 45) years who underwent a CT-guided CNB were compared with 31 men and 33 women aged 9 to 81 (mean, 53) years who underwent an incisional biopsy. All specimens h...
NMR in biomedicine
Gliomas are routinely graded according to histopathological criteria established by the World Health Organization. Although this classification can be used to understand some of the variance in the clinical outcome of patients, there is still substantial heterogeneity within and between lesions of the same grade. This study evaluated image-guided t...
Catheterization and cardiovascular interventions : official journal of the Society for Cardiac Angiography & Interventions
We report the successful biopsy of a right atrial fatty mass using CARTO 3-dimensional electro-anatomic mapping fused with cardiac MRI. Fluoroscopic guidance within the cardiac chambers lacks precision and therefore risks geographical miss of the intended target and cardiac perforation. CARTO mapping fused with cardiac MRI facilitated precise navig...

When magnetic resonance imaging/transrectal ultrasound fusion guided biopsy detects isolated atypical small acinar proliferation on index biopsy, early rebiopsy is unlikely to detect clinically significant prostate cancer. Cores that retarget areas of previous atypical small acinar proliferation are more effective than random rebiopsy cores.
Our preliminary experience shows that office-based percutaneous renal biopsy using a novel transducer for FUT is safe and effective. An international multicentre study is planned to confirm these preliminary results.
