The purpose of this study was to investigate the manifestations of irAEs on body imaging in patients with advanced melanoma treated with ipilimumab. One-hundred forty-seven patients with advanced melanoma (59 women, 88 men; median(More)
Diffuse large B cell lymphoma (DLBCL) is the most common histological subtype of Non-Hodgkin's lymphoma. As treatments continues to evolve, so do imaging strategies, and positron emission tomography (PET) has emerged as the most important imaging tool to guide oncologists in the diagnosis, staging, response assessment, relapse/recurrence detection,and(More)
UNLABELLED Cytotoxic chemotherapy, hormonal therapy and molecular targeted therapy are the three major classes of drugs used to treat breast cancer. Imaging modalities such as computed tomography (CT), magnetic resonance imaging (MRI), (18)F-FDG positron emission tomography (PET)/CT and bone scintigraphy each have a distinct role in monitoring response and(More)
Aortic infections are uncommon clinical entities, but are associated with high rates of morbidity and mortality. In this review, we focus on the cross-sectional imaging appearance of aortic infections, including aortic valve endocarditis, pyogenic aortitis, mycotic aneurysm and aortic graft infections, with an emphasis on CT, MRI and PET/CT appearance.(More)
OBJECTIVE The purpose of this article is to provide a comprehensive review of the role of imaging modalities other than PET/CT in the management of Hodgkin lymphoma (HL). PET/CT is the imaging modality of choice in the management of Hodgkin's lymphoma (HL). However, imaging modalities other than PET/CT such as plain radiographs, ultrasound, CT, MRI and(More)
OBJECTIVE The purpose of this article is to provide a comprehensive review of the imaging features of extracutaneous melanomas.
