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: The brain morphology and structure were normal; no abnormal density shadows were seen in the brain parenchyma, and FDG uptake was normal.
There was no widening of the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical and showed no obvious abnormalities.
The ethmoid and maxillary sinuses showed thickening of the mucosa bilaterally, but the sinus walls were intact.
The nasopharyngeal walls were 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 normal FDG uptake.
The bilateral palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
The thyroid gland is normal in shape and size, with uneven density, showing punctate and small nodular low-density lesions.
FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
Scattered solid micronodules with clear borders, approximately 0.2-0.4 cm in diameter, were seen in both lungs.
FDG uptake was normal in all lungs.
No pleural thickening was seen bilaterally, and there was no pleural effusion or pneumothorax.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
A cystic lucent shadow was seen near the trachea in the superior mediastinum.
The cardiac silhouette was normal.
The esophagus was not dilated, and the esophageal wall was not significantly thickened or swollen.
FDG uptake was normal.
The liver was normal in shape and size, with smooth liver margins and no widening of the hepatic fissure.
Calcification was present in the right lobe of the liver.
No significant abnormal density shadows were seen in the remaining liver parenchyma.
FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder was normal in shape and size, with no significant thickening of the gallbladder wall, and no significant abnormalities in FDG metabolism.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no significant abnormalities in FDG uptake.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size, with no significant abnormal density shadows in the parenchyma, no widening of the renal pelvis, calyces, or ureters, and no significant abnormalities in FDG uptake.
Bilateral adrenal gland imaging showed no significant abnormalities.
The stomach was poorly distended, with no significant thickening of the stomach wall, and no significant abnormalities in FDG uptake.
The intestines were poorly distended; post-rectal cancer surgery, FDG uptake in the surgical area was normal, and no significant thickening or mass was observed in the remaining intestinal wall; FDG uptake was physiological.
The prostate gland is normal in size and shape, with uneven density and punctate calcifications.
FDG metabolism is not abnormally elevated.
The bladder wall shows no abnormal thickening, and no obvious positive stones are observed.
Calcification is present in the tunica vaginalis of the right testis.
No enlarged lymph nodes are seen in the abdominoperineal and retroperitoneal regions.
No significant fluid accumulation is observed in the abdomen or pelvis.
Calcification of the nuchal ligament is present.
The spinal alignment is normal, with some vertebral body margin osteophytes and L3/4, L4/5, and L5/S1 intervertebral disc bulges.
Systemic bone FDG metabolism is normal.

Impression

1. Uneven prostate density with punctate calcifications; FDG uptake normal; no clear space-occupying lesion. Please analyze in conjunction with contrast-enhanced MRI images from another hospital; biopsy may be necessary.

2. Postoperative rectal cancer surgery; no obvious signs of tumor recurrence.

3. Scattered chronic inflammatory micronodules (solid) in both lungs. Tracheal diverticulum.

4. Calcification in the right lobe of the liver. Calcification in the tunica vaginalis of the right testis.

5. Spinal degenerative changes. L3/4, L4/5, L5/S1 intervertebral disc bulge.

6. Nodular goiter; ultrasound follow-up recommended.

7. Chronic inflammation of bilateral ethmoid and maxillary sinuses. Cranial FDG imaging normal.

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.
