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; midline shift was not observed.
Both eyes were symmetrical with no obvious abnormalities.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasal septum was slightly deviated; the nasopharyngeal wall was not thickened, and FDG uptake was normal.
The pharyngeal recesses were symmetrical, 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.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
Thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
Lung markings are clear bilaterally; several solid nodules are present in both lungs, the largest being approximately 0.8 cm in diameter; FDG uptake is normal.
A blurred patchy shadow with increased FDG uptake is present in the right lower lobe (SUVmax = 2.1); scattered linear lesions are present bilaterally; FDG uptake is normal.
The pleura is slightly thickened bilaterally; there is no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette is normal.
Some arterial walls show calcification (including the coronary arteries).
The esophagus is not dilated; the esophageal wall is not significantly thickened or has a mass; FDG uptake is normal.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissure.
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, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormalities in FDG uptake.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size.
A cystic lesion was observed in the right renal parenchyma, approximately 1.9 cm in diameter, with absent FDG uptake.
The renal pelvis, calyces, and ureter were not widened, and FDG uptake was normal.
The left adrenal gland was enlarged with increased FDG uptake, with SUVmax = 2.5.
No obvious abnormalities were observed in the right adrenal gland upon imaging.
The stomach was poorly filled, with slight thickening of the walls of the cardia, part of the gastric body, and the antrum.
FDG uptake was mildly increased, with SUVmax=2.1.
Intestinal filling was unsatisfactory, with increased FDG uptake in some parts of the intestine, SUVmax=5.0.
The bladder was poorly filled, with no obvious positive stones.
The prostate was enlarged, with a long diameter of approximately 5.6cm, containing dense nodules.
Irregular patchy slightly low-density shadows of the prostate were observed, more pronounced in the right peripheral zone, with increased FDG uptake, SUVmax=10.6, covering an area of approximately 5.0*3.2*5.6cm, invading the seminal vesicles, and the boundary with the adjacent rectum was indistinct.
Overall bone density was decreased, the spinal alignment was normal, with osteophyte formation at the margins of some vertebral bodies, and L4/5 intervertebral disc bulging.
Patchy FDG uptake was observed bilaterally around the shoulders, with an SUVmax of 3.7.
Increased FDG uptake was also observed in the S5 vertebral body and the left inferior pubic ramus, with an SUVmax of 5.2.

Impression

1. a. Prostatic mass with elevated FDG metabolism, suggesting continued activity of prostate cancer after treatment, invading the seminal vesicles. Benign prostatic hyperplasia with calcification. b. Bone metastasis to the S5 vertebral body and left subpubic ramus.

2. Inflammation in the right lower lobe of the lung, chronic inflammatory nodules in both lungs. A few post-inflammatory lesions in both lungs. Slight thickening of the pleura bilaterally. Calcification of some arterial walls (including coronary arteries).

3. Left adrenal hyperplasia. Right renal cyst.

4. Chronic inflammatory changes in part of the gastric wall and intestines; please follow up with endoscopy.

5. Osteoporosis, degenerative changes in the spine, L4/5 intervertebral disc bulge. Bilateral shoulder periarthritis.

6. Age-related brain, deep lacunar infarcts.

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.
