Summary

To investigate the sensitivity of the \[18F\]fluoroethylcholine (FEC) Positron-Emission-Tomography/ Magnetic Resonance Imaging (PET/MRI) method in tumour detection and location (side assignment, encapsulation, invasion of the seminal vesicle) and detection of affected lymph nodes, and to compare these with presently used detection procedures (needle biopsy, digital rectal examination, transrectal ultrasound, and pre-therapeutic assessment), with a view to finding out whether the \[18F\]fluoroethylcholine PET/MRI method is comparable to, or superior to, the established method. Postoperative histology served as the standard of reference.

OTHER

18F-Ethylcholine Positron Emission Tomography (FEC-PET)

PET scans were performed on a LSO scanner (ECAT ACCEL, Siemens, Erlangen, Germany) by using a multiphase protocol starting with a "cold" transmission scan of the lower pelvis. This was followed by a list mode emission scan with 10 frames à 1 minute starting immediately after the administration of 3.3MBq \[18F\]Fluoroethylcholine chloride (FEC; Eckert \& Ziegler EURO-PET Berlin GmbH) as a bolus through the cubital vein. After a short gap due to computer processing time the whole body scan was performed starting at the upper thoracic aperture down to the proximal femur. Acquisition parameters were 3 minutes emission scan and 2 minutes transmission scan for each bed position. Therefore the prostate region was scanned again at 45 minutes p.i. (post injection) A delayed local acquisition at 65 minutes over the lower pelvis with 6 minutes emission and 2 minutes transmission finished the diagnostic acquisition procedure.

OTHER

Endorectal Magnetic Resonance Imaging (1.5Tesla) (eMRI)

The MRI examination was performed on a 1.5Tesla MRI system (Gyroscan ACS-NT, Philips, Hamburg, Germany) with combined QBody and endorectal coil. Pelvic assessment and lymph node staging was effected with 5mm T2 weighted (T2w) turbo spin echo (TSE) transversal and a coronal short-tau inversion recovery (STIR) sequence. For prostate assessment, 3mm endorectal T2w spin echo (SE) sagittal, transversal and coronal sequences were acquired.
