Whole-body 18F-FDG PET/CT scan in a patient with Bladder 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, and resting, a whole-body PET/CT scan was performed.
The whole-body tomographic images showed: The brain morphology and structure were normal; no abnormal density shadows were seen in the brain parenchyma, and FDG uptake was not significantly abnormal.
The ventricles, sulci, fissures, and cisterns were not widened; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no obvious abnormalities.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasopharyngeal wall showed no thickening, and FDG uptake was not abnormal.
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 bilateral palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The laryngopharynx morphology and structure were normal.
Thyroid gland: Normal in shape and size, with slightly uneven density; FDG uptake not abnormal.
No enlarged lymph nodes in the bilateral deep cervical spaces or submandibular region.
A few patchy or linear shadows in the right lower lobe; FDG uptake not abnormal.
Slight localized pleural thickening bilaterally; no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes in the bilateral hilar and mediastinal regions.
Some arterial walls show calcification.
Cardiac shadow: No abnormalities observed.
Esophageal dilation; no significant thickening or mass in the esophageal wall; FDG uptake not increased.
No significant abnormal density in the bilateral breasts; FDG metabolism not abnormal.
Liver: No significant abnormalities in shape and size; smooth liver margins; no widening of the hepatic fissure; no significant abnormal density shadows in the liver parenchyma; FDG uptake not abnormal.
No significant widening of the main portal vein; no dilation of intrahepatic or extrahepatic bile ducts.
Gallbladder: No abnormalities in shape or size, no thickening of the gallbladder wall, and no abnormalities in FDG uptake.
Pancreas: Normal shape, no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormalities in FDG uptake.
Spleen: No abnormalities in shape, size, density, or FDG uptake.
Kidneys: Normal shape and size, no obvious abnormal density shadows in the parenchyma, no widening of the renal pelvis, calyces, or ureters, and no obvious abnormalities in FDG uptake.
Bilateral adrenal glands: No obvious abnormalities observed on contrast.
Stomach: Poor distension, no obvious thickening of the stomach wall, and no obvious abnormalities in FDG uptake.
Intestinal distension: Poor continuous FDG metabolism in the colon and rectum, SUVmax = 13.5.
Uterus: Normal shape, no abnormal density shadows, and no abnormally increased FDG uptake.
No abnormal FDG metabolism was observed in the bilateral adnexa.
Post-bladder cancer surgery, no abnormal thickening of the bladder wall was observed, and no obvious positive stones were seen within the bladder.
No enlarged lymph nodes were observed in the abdominopelvic region or retroperitoneal region.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral body margin osteophytes, and L4/5 and L5/S1 intervertebral disc bulging with posterior margin calcification.
No abnormalities were observed in systemic bone FDG metabolism.

Impression

1. Post-bladder cancer surgery, no signs of tumor recurrence observed; specialist follow-up recommended.

2. Chronic inflammation and sequelae in the right lower lobe of the lung. Slight localized pleural thickening bilaterally. Calcification of some arterial walls.

3. Physiological or inflammatory uptake of the colorectal tissue; endoscopic follow-up recommended. (The right hydronephrosis and right renal cystic lesion shown on ultrasound from another hospital were not clearly visualized.)

4. Partial vertebral osteophyte formation. L4/5 and L5/S1 intervertebral disc bulge with posterior margin calcification.

5. No obvious abnormalities seen on cranial FDG scintigraphy.

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.
