Pre-operative sentinel lymph node localization in breast cancer with superparamagnetic iron oxide MRI: the SentiMAG Multicentre Trial imaging subprotocol.

Objective: Sentinel lymph node biopsy (SLNB) with a superparamagnetic iron oxide (SPIO) tracer was shown to be non-inferior to the standard combined technique in the SentiMAG Multicentre Trial. The MRI subprotocol of this trial aimed to develop a magnetic alternative for pre-operative lymphoscintigraphy (LS). We evaluated the feasibility of using MRI following the administration of magnetic tracer for pre-operative localization of sentinel lymph nodes (SLNs) and its potential for non-invasive identification of lymph node (LN) metastases.

Targeted lymph node biopsy in mediastinoscopy using 3D FDG-PET/CT movies: a feasibility study.

In non-small-cell lung cancer, positive lymph nodes with increased fluorodeoxyglucose (FDG) uptake may be missed by mediastinoscopy. Lack of pathological confirmation may lead to radical, but unnecessary lung surgery. To minimize these false-negative results, the feasibility and potential value of three-dimensional (3D) FDG-PET/computed tomography (CT) movies were investigated to improve targeted lymph node biopsy during mediastinoscopies.

Cardiac imaging in a symptomatic patient with multiple coronary artery-left ventricular microfistulae.

We present the case of a 44-year-old woman with acute coronary syndrome and multiple coronary artery-left ventricular microfistulae at angiography. To evaluate the clinical significance of this observation and to obtain further insights into this rare disease, the patient was further examined with echocardiography and both magnetic resonance imaging and single-photon emission computed tomography, which showed considerable abnormalities.
