MRI delineates complexities of preterm infant brain
Investigators have successfully used imaging on adults who survived preterm birth; neurological scans performed on infants, while they are still in the danger zone, is much trickier. MRI may offer the best way to effectively diagnose certain pathologies in these children.

Sexual healing: Imaging takes a roll in the hay with human relations
The amorous amygdala, the come-hither cerebellum -- this is your brain on sex. Using MRI and PET, neuroscientists get closer to determining how and why we lust. Meanwhile, imaging specialists take an intimate look at the mechanics of arousal response -- all in the name of promoting good sex.

Scintimammography augments traditional cancer detection methods
Radiographically dense breasts continue to pose a challenge to women's imaging specialists. The alternative imaging options that have been proposed include computed radiography for mammography, as well as ultrasound, MRI, and scintimammography. A study in the latest issue of the Journal of Nuclear Medicine has suggested taking the latter modality one step further, with a dedicated breast camera.

Study offers strategy for safe MRI with pacemakers
Cardiac and MRI specialists have joined together to develop a seven-step guideline for cautiously and effectively imaging patients with pacemakers. They devised this risk/benefit profile after performing a prospective study of 54 pacemaker patients who required MRI or MR angiography (MRA).

PET/CT images of F-18 AlF-NOTA-BCP137 in patients with hepatocellular carcinoma (HCC) and immunofluorescence analysis of patient tissues. (A) F-18 AlF-NOTA-BCP137 PET/CT images before and after immunotherapy for patient 1 and patient 2. (B) F-18 AlF-NOTA-BCP137 PET/CT and MR images of patient 3 (left panels) after one cycle of immunotherapy. PET images showed higher uptake by tumor and spleen, and PET result was evaluated as positive; therefore, the patient was considered to be responder to treatment and underwent surgical resection. Representative images of hematoxylin and eosin (HE) staining and multiplex immunofluorescence of CD8 and CD137 (right panels) in HCC tumor and adjacent normal tissues of patient 3 after surgery. Nuclei were stained with 4′,6-diamidino-2-phenylindole. Primary tumors are indicated by white arrows, and increased thyroid uptake is indicated by red arrow in PET images.
