Prostate Cancer Metastatic to Bone
Conditions
Brief summary
An improved diagnosis of bone metastases in prostate cancer patients can have a significant impact on treatment strategy and probably survival as well. The primary purpose of the project is to determine the diagnostic accuracy of bone SPECT-CT, choline-PET-CT, PSMA-PET-CT, NaF-PET-CT and Whole-body MRI in the diagnosis of bone metastases in prostate cancer patients.
Detailed description
The project is a prospective diagnostic test accuracy study. The project takes place at Herlev Hospital and is a collaboration between the Department of Radiology and the Department of Clinical Physiology and Nuclear Medicine. The investigators want to include 300 prostate cancer patients referred to our standard diagnostic imaging (NaF-PET-CT scan) by the clinicians. In addition to the standard diagnostic imaging (NaF-PET-CT-scan), two project will be performed on all participants. The project has three arms with the following scanning combinations: A) Whole-body MRI + SPECT-CT B) Whole-body MRI + Cholin-PET-CT C) Whole-body MRI + PSMA-PET-CT The recruitment of project participants takes place on the day when the patients are undergoing a NaF-PET-CT scan in the course of regular clinical practice at our institution. All readers are experienced radiologists or specialists in nuclear medicine. Patient identification on each scan will be anonymized and the reader will not have access to clinical and biochemical information or previous imaging studies.

Inclusion criteria
A subject will be eligible for project participation if he meets all of the following criteria: * Is either 1) a newly diagnosed prostate cancer patient in clinical suspicion of bone metastases or 2) a previously diagnosed prostate cancer patient in clinical suspicion of progression in the form of bone metastases. The subject must have been referred to the standard diagnostic imaging (18F-NaF-PET-CT) at our institution for bone metastases. * The prostate cancer diagnosis must be biopsy-proven * The subject is willing and able to comply with the protocol as judged by the investigator
Exclusion criteria
A subject will be excluded from the protocol if he meets one or more of the following criteria: * Has prior malignancy, except for adequately treated basal cell or squamous cell skin cancer * Has pacemaker or implanted devices (eg. cardiac valves, neurostimulator or insulin pump) that cannot be removed, metal clips/metal prostheses from surgery that are not MRI compatible or metallic foreign bodies in the eye (MRI
