Positron emission tomography/magnetic resonance imaging (PET/MRI) in the Evaluation of Brain Tumors: Current status and future Prospects
Various designs of positron emission tomography/magnetic resonance imaging (PET/MRI) systems have been recently introduced into clinical practice, which have overcome technical challenges concerning the fusion of PET and MRI. This review summarizes the literature on the use of PET and MRI as well as addresses the potential benefit and contributions of hybrid PET/MRI in neuro-oncology. Multiple functional parameters derived from this novel technology are appealing as imaging biomarkers because of its noninvasive nature, complementary information and quantitative capability.

PET/MRI in Lung Cancer
Imaging plays an important role in the diagnosis and management of lung cancer, which is the leading cause of cancer-related death in the world.1 Radiography is often the initial modality of diagnosis, but detection depends on the size and density of nodules. The sensitivity of detection may be improved by using the dual-energy subtraction technique, which generates a soft tissue reconstruction that is free of overlapping chest wall and bony structures, or by using tomosynthesis. Computed tomography (CT) has become the established modality for the screening, diagnosis, and staging of lung cancers. (Source: Seminars in Roentgenology)

Positron Emission Tomography-Magnetic Resonance Imaging in Oncologic Diseases of the Male and Female Pelvis
The human pelvis harbors a variety of organs and structures that can be at the origin of developing neoplasms. The clinical and diagnostic workup, the staging, and the appropriate treatment and disease follow-up of these neoplasms are diverse and complex and depend on the organ and tumor type, among other factors. Similarly, the individual diagnostic algorithms and the value of imaging in these algorithms vary between organs and tumor types. The possibility to directly access the target tissue and organ via percutaneous, transrectal, transvaginal, or transurethral approaches offers many options for the diagnosis and stagin...
