AIM: To prospectively evaluate the clinical impact and the diagnostic performance of FCH-PET/CT in patients with occult biochemical recurrence of prostate cancer (PCa). MATERIALS AND METHODS: Results of 179 patients (mean PSA = 7.5ng/mL) with negative/inconclusive results of pelvic-MRI and of bone-scintigraphy were analysed. To determine the impact of FCH-PET/CT on diagnostic thinking and on patient management, the referring physicians prospectively filled-in a 1st and 2nd questionnaire related to patient's planned management before and after FCH-PET/CT...

OBJECTIVES: To assess the additional diagnostic value of 18F-fluorocholine PET imaging in preoperative localization of pathologic parathyroid glands in clinically manifest hyperparathyroidism in case of negative or conflicting ultrasound and scintigraphy results. METHODS: A retrospective, single-institution study of 26 patients diagnosed with hyperparathyroidism. In cases where ultrasound and scintigraphy failed to detect the location of an adenoma in order to allow a focused surgical approach, an additional 18F-fluorocholine PET scan was performed and its results were compared with the intraoperative findings...

An 80-year-old woman was evaluated with F-fluorocholine PET/CT in suspicion of a parathyroid adenoma. No focal parathyroid tracer uptake suggestive of adenoma was found, and instead a unilateral multinodular goiter without elevated F-fluorocholine uptake was diagnosed. In addition, focal uptake was found in a cutaneous nodule dorsally on the right shoulder. Upon pathological evaluation, this proved to be a malignant melanoma.

A 76-year-old man with metastatic prostate cancer and back pain was referred for palliative radiotherapy. Staging F-fluorocholine PET/CT scan revealed fluorocholine-avid prostate mass, extensive lymphadenopathy, lung nodules, and extensive osteolytic lesions throughout the axial skeleton. Prostate cancer bone metastases are predominantly sclerotic in nature. We present F-fluorocholine PET/CT imaging of prostate cancer with very rare lytic bone metastases.

A case of follicular thyroid cancer with intense focal Methionine uptake on 11C-Methionine PET/CT is reported here. The use of 11C-Methionine PET in differentiated thyroid cancer is currently being investigated as a surrogate tracer compared to the more widely used 18F-FDG PET. This case illustrates the potential incremental value of this modality, not only in the localizing of parathyroid adenoma, but also indicating that 11C-Methionine PET might have a potential of increasing the pretest likelihood of thyroid malignancy in a cold nodule with highly increased Sestamibi uptake...

OBJECTIVE: The purpose of this study was to determine whether integrated 18F-fluorocholine (FCH) PET whole-body MRI (PET/WBMRI) depicts lymph node and distant metastases in patients with high-risk prostate cancer more frequently than does conventional staging. SUBJECTS AND METHODS: A prospective study included 58 patients with untreated high-risk prostate cancer. After conventional staging (CT and bone scintigraphy), patients underwent FCH PET/WBMRI (n = 10) or FCH PET/CT and WBMRI (n = 48)...

The association between choline uptake and androgen receptor (AR) expression is suggested by the upregulation of choline kinase-alpha in prostate cancer. Recently, detection of AR aberration in cell-free DNA as well as early 18F-fluorocholine positron emission tomography/computed tomography (FCH-PET/CT) were associated with outcome in metastatic castration-resistant prostate cancer (mCRPC) patients treated with abiraterone and enzalutamide. We aimed to make a direct comparison between circulating AR copy number (CN) and choline uptake at FCH-PET/CT...

PURPOSE: Inadequate clinical target volume (CTV) definition is likely to be a major contributing factor to local recurrence (LR) rate after radiotherapy. Our aims were to identify sites of prostate cancer LR in biochemical recurrence post-prostatectomy using (18)F-Fluorocholine (18F-FCH) positron emission tomography/computed tomography (PET/CT) and to compare different CTV-delineation guidelines in a cohort of postoperative patients. MATERIAL AND METHODS: Thirty-six patients presenting with LR within the prostatic bed on 18F-FCH PET/CT between 10/2011 and 06/2016 were included in this retrospective study...

Endometriosis is a debilitating disease that still needs surgery to be confirmed. Endometriosis is associated with increased plasma levels of phosphatidylcholines. (18)F-fluorocholine ([(18)F]FCH) is a radiopharmaceutical that is metabolized to phosphatidylcholine inside the cells and can be traced by positron emission tomography (PET). Here we evaluate [(18)F]FCH as a potential tool for the noninvasive diagnosis of peritoneal endometriosis. Adult female Wistar rats had autologous uterine fragments dissected and grafted to the peritoneal wall to model peritoneal endometriosis...

Two patients with castrate-resistant prostate cancer and symptomatic skeletal metastases underwent F-fluorocholine PET/CT prior to treatment with Ra-dichloride to reveal additional active lesions in the prostate gland and lymph nodes. Subsequent scans performed at the midpoint and end of Ra-dichloride therapy showed resolution of this soft tissue activity alongside declining bone lesion activity. Concomitant increases in plasma interleukin 6 were detected, suggesting that immune system activation may have mediated the soft tissue response...

We present 3 cases of patients with castration-resistant prostate cancer and bone metastases treated with Ra, belonging to our prospective and multicenter ChoPET-Rad study. All patients underwent clinical, hematological, and biochemical monitoring between each Ra administration. Initial and follow-up F-fluorocholine PET/CT and Tc-biphosphonate bone scintigraphy were performed previously and after the third Ra administration. Both techniques correctly established the response to treatment, in agreement to the biochemical response, although differences in the disease expression (concordant and discordant patterns) were found because of the different radiotracer biodistribution and molecular information derived from them...

A 72-year-old man with prostate cancer (stage T3b, Gleason score 7) treated by radical prostatectomy was found to have biochemical failure (prostate-specific antigen 8.5 ng/mL) and a suspicious growing nodularity at the left prostate bed on MRI. F-fluorocholine PET/CT failed to demonstrate any site of uptake suggestive of malignancy. A bone scan did exclude bone metastases. Ga-PSMA PET/CT revealed various positive lymph nodes in the supraclavicular, mediastinal, and hilar regions. This was confirmed on F-DCFPyl PET/CT, with the addition of a suspicious right axillary lymph node...
