MR-guided breast biopsy

PET-guided breast biopsy.

Molecular imaging, using positron emission tomography (PET), has become an integral step in the evaluation of many patients with malignancy. However, its use in patients with breast cancer has been limited by the lower levels of (18) F-fluorodeoxyglucose (FDG) uptake in some breast malignancies compared to other cancers, the small size of many breast cancers, and the need for biopsy under PET g...

Digital breast tomosynthesis-guided biopsy: preliminary experience

Stereotactically guided breast biopsy: a review

The aims of this review are to compare and contrast the available stereotactic equipment, and to describe the variety of needle types used and their affect on pathological results and subsequent patient management. Initial stereotactic devices were "added-on" to analogue mammography units and have been replaced by prone or ducubitus equipment using digital image acquisition. Biopsies use either...

MR imaging--guided breast ablative therapy.

The integration of imaging and thermal therapy can provide a minimally invasive or even noninvasive alternative to breast surgery for small tumors. Ongoing trials seek to show safety and efficacy for laser, radiofrequency, microwave, cryoablation, and focused ultrasound surgery. To be successful, these therapies must achieve equivalent or even greater efficacy as surgical outcomes and must demo...

Realtime MR guided endomyocardial biopsy with an active visualization bioptome

Background Invasive endomyocardial biopsy is an important tool to diagnose cardiomyopathy. But the diagnostic yield is low because the procedure is performed ‘blind’ using, particularly in processes characterized by heterogeneous myocardial involvement. MRI tissue characterization techniques, using late gadolinium enhancement or T1 mapping for example, can identify affected regions and guide bi...
