Whole-body 18F-FDG PET/CT scan in a patient with Prostate Cancer taken from the PETWB-REP dataset. The following English report (translated from original Chinese) is taken verbatim from the public dataset and has not been modified or otherwise checked for accuracy (see the end for citation).

Findings

After fasting and intravenous injection of 18F-FDG, a whole-body PET/CT scan was performed.
The whole-body scan showed: Brain morphology and structure were normal, with punctate, slightly low-density shadows in the deep brain regions; FDG metabolism was normal.
The ventricles, sulci, fissures, and cisterns were widened, but local density and FDG uptake were normal; there was no midline shift.
The eyeballs were symmetrical bilaterally, with no obvious abnormalities.
The maxillary sinus mucosa was thickened bilaterally, but the sinus walls were intact.
The nasopharyngeal walls were not thickened, and FDG uptake was normal.
The pharyngeal recesses were symmetrical bilaterally, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake bilaterally.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
Thyroid gland morphology and size are normal.
A low-density nodule, approximately 1.6*1.4cm in size, is present in the left lobe, with increased FDG uptake (SUVmax = 1.9).
No enlarged lymph nodes are seen in the bilateral deep cervical spaces or submandibular region.
Lung markings are clear bilaterally.
Several solid nodules are present in the right upper lobe, the largest approximately 0.3cm in diameter, with no abnormal FDG uptake.
Calcification is present in the lateral basal segment of the left lower lobe, and a few linear lesions are present in the inferior lingular segment of the left upper lobe and both lower lobes, with no abnormal FDG uptake.
Slight pleural thickening is present bilaterally, with no pleural effusion or pneumothorax.
No significantly enlarged lymph nodes are seen in the bilateral hilar and mediastinal regions.
Cardiac findings are normal.
Calcification is present in some arterial walls (including the coronary arteries).
The esophagus is not dilated, and the wall is not significantly thickened or swollen; FDG uptake is not increased.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissures.
Plain CT scan showed no obvious abnormal density shadows in the liver parenchyma, and FDG uptake was normal.
The main portal vein showed no obvious widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape and size, but the gallbladder wall was thickened, and local FDG uptake was normal.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct was not widened, and FDG uptake was normal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters were not widened, and FDG uptake was normal.
Bilateral adrenal gland imaging showed no obvious abnormalities.
Stomach distension is poor, with slight thickening of the antral wall and mildly increased FDG uptake (SUVmax = 1.9).
Intestinal distension is unsatisfactory, but physiological uptake is observed.
Bladder distension is adequate, with an inserted urinary catheter.
Calcification of the tunica vaginalis is present on the left side.
The prostate is enlarged, containing punctate dense shadows.
An irregular, slightly low-density mass with indistinct borders is present, with increased FDG uptake (SUVmax = 8.7) and an uptake range of approximately 4.7*3.1*3.5cm.
Multiple lymph nodes are visible in both pelvic walls, the largest being on the left side with a short diameter of approximately 1.3cm, showing increased FDG uptake (SUVmax = 4.1).
The spinal alignment is normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulges.
Increased density is observed on the right sacroiliac joint surface, but no abnormal FDG uptake is seen.
Focal FDG uptake was observed in the left segment of the T12 vertebral body, with SUVmax = 4.5.
No abnormalities were found in systemic bone marrow FDG metabolism.

Impression

1. a. Benign prostatic hyperplasia with calcification; prostatic mass with increased FDG metabolism, suggestive of prostate cancer. Left pelvic wall lymph node metastasis, right pelvic wall lymph node metastasis to be ruled out. b. Focal increased FDG metabolism in the left part of the T12 vertebral body, please combine with MRI to rule out metastasis.

2. Chronic inflammatory micronodules in the right upper lobe of the lung. Calcification in the left lower lobe of the lung, a few post-inflammatory remnants in both lungs. Slight thickening of the pleura bilaterally. Calcification of some arterial walls (including coronary arteries).

3. Chronic cholecystitis. Calcification in the left testicular tunica vaginalis.

4. Chronic inflammatory changes in the antrum of the stomach, please combine with endoscopic follow-up.

5. Degenerative changes in the spine, L4/5 and L5/S1 intervertebral disc bulge. Osteitis condensans of the right sacroiliac joint.

6. A low-density nodule in the left lobe of the thyroid gland with elevated FDG metabolism, suggestive of an adenomatous nodule; please confirm with ultrasound examination.

7. Elderly patient with deep lacunar infarcts and chronic inflammation of both maxillary sinuses.

This case is from PETWB-REP, a curated dataset of whole-body 18F-FDG PET/CT scans and corresponding radiology reports from 490 patients with a broad spectrum of malignancies. The data were retrospectively collected from patients who underwent clinically indicated whole-body 18F-FDG PET/CT scans at the Shanghai Universal Medical Imaging Diagnostic Center between 2021 and 2024.
