Optimized Whole-Body PET MRI Sequence Workflow in Pediatric Hodgkin Lymphoma Patients.

F-FDG PET/MRI might be the diagnostic method of choice for Hodgkin lymphoma patients, as it combines significant metabolic information from PET with excellent soft-tissue contrast from MRI and avoids radiation exposure from CT. However, a major issue is longer examination times than for PET/CT, especially for younger children needing anesthesia. Thus, a targeted selection of suitable whole-body MRI sequences is important to optimize the PET/MRI workflow.

PET/CT in malignant melanoma: a two-tiered healthcare system? Updated healthcare situation regarding initial staging of malignant melanoma with PET/CT.

Background: Patients with stage IIC malignant melanoma are recommended to undergo cross-sectional imaging for initial staging. PET/CT is superior to other methods regarding its diagnostic accuracy of the tumor spread in stage III. So far there is no meaningful data on the nationwide availability, usage and cost recovery of this imaging technique.

Impact of complete surgical resection on outcome in aggressive non-Hodgkin lymphoma treated with immunochemotherapy.

Background: Surgical resection is considered to be of purely diagnostic value in aggressive lymphoma. Evidence for an impact on outcome is scant and restricted to retrospective observations.

Methods: In the "Positron Emission Tomography-guided Therapy of Aggressive non-Hodgkin Lymphomas" (PETAL) trial, patients with a negative baseline positron emission tomography (PET) scan were documented in a prospective observational substudy.
