Background After focused high dose radiotherapy of brain metastases, differentiation
between tumor recurrence and radiation-induced lesions by conventional MRI is …

Background Conventional MRI is the standard method to diagnose recurrence of brain
metastases after radiation. However, following radiation therapy, reactive transient blood …

PET using the amino-acid O-(2-18 F-fluoroethyl)-l-tyrosine (18 F-FET) is gaining increasing
interest for brain tumour management. Semi-quantitative analysis of tracer uptake in brain …

Abstract Purpose O-(2-[18 F] fluoroethyl)-l-tyrosine ([18 F] FET) is an established positron
emission tomography (PET) tracer for brain tumor imaging. This study explores the influence …

Purpose Radiographic changes of brain metastases after stereotactic radiosurgery (SRS)
can signify tumor recurrence and/or radiation necrosis (RN); however, standard imaging …

Amino acid PET is an established method to assist differential diagnosis of therapy-related
changes versus recurrence in gliomas. However, its diagnostic value in brain metastases is …

Background Patients with metastatic cancer to the brain have a poor prognosis. In clinical
practice, MRI is used to delineate, diagnose and plan treatment of brain metastases …
