Whole-body 18F-FDG PET/CT scan in a patient with Colon 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 images showed: Normal brain morphology and structure; no abnormal density shadows were seen in the brain parenchyma; no significant abnormalities were observed in FDG uptake.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical and showed no significant abnormalities.
A small amount of mucosal thickening was observed in the left maxillary sinus, but no thickening was observed in the mucosa of the remaining paranasal sinuses, and the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; the palatine tonsils were symmetrical, and FDG uptake was physiological.
The laryngopharynx showed no abnormalities in morphology and structure.
The parotid and submandibular glands were normal in morphology and density, and showed physiological FDG uptake.
Focal FDG uptake was observed in the left upper alveolar ridge, with SUVmax = 7.3.
The thyroid gland was normal in morphology and size, with uniform density, and no abnormalities in FDG uptake.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, or submental region.
The lung markings are clear.
An odd lobe is present in the right upper lobe, with small solid nodules (approximately 0.2 cm in diameter) in the apical and posterior segments of the right upper lobe; no abnormal FDG uptake was observed.
A few linear lesions are present in both lungs; FDG uptake is normal.
No pleural thickening or pleural effusion/pneumothorax is observed bilaterally.
No significantly enlarged lymph nodes are seen in the hilum or mediastinum bilaterally.
The cardiac silhouette is normal.
Partial arteriosclerosis is present.
The esophagus is not dilated, and the wall is not significantly thickened or swollen; FDG uptake is normal.
No significant masses or nodules are seen in either breast; FDG metabolism is normal.
The liver is normal in shape and size, with smooth borders and no widening of the hepatic fissure.
A slightly low-density lesion (approximately 1.9 cm in long diameter) is present near the diaphragm in the left lobe; FDG uptake is normal.
The main portal vein is not significantly widened; no dilation of intrahepatic or extrahepatic bile ducts is observed.
The gallbladder showed no abnormalities in shape or size, but increased density within the gallbladder.
The gallbladder wall was not 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 contrast was normal.
The stomach was adequately filled, with slight thickening of the gastric antrum wall and mildly increased FDG uptake (SUVmax = 2.6).
Post-colon EMR, a metal clip was seen in the sigmoid colon, but no abnormal FDG metabolism was observed in the surgical area; no obvious space-occupying lesions were seen in the remaining intestinal segments, and FDG metabolism was normal.
The uterus was normal in shape and size, with no abnormal density shadows and normal FDG uptake.
No obvious abnormalities were seen in the bilateral adnexa.
The bladder was poorly filled, but no obvious positive stones were seen within it.
No enlarged lymph nodes were observed in the abdominal cavity, pelvic cavity, 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.
L3/4 intervertebral disc bulge was observed, but no abnormal FDG uptake was detected.
Extensive FDG uptake was observed throughout the medullary cavity, with SUVmax = 5.6.

Impression

1. Post-EMR changes in the colon: No abnormal FDG metabolism was observed in the sigmoid colon metal clip area; no obvious space-occupying lesions were seen in the remaining intestinal segments, and FDG metabolism was normal. Follow-up colonoscopy is recommended.

2. Right upper lobe aberrant lobe formation; chronic inflammatory micronodules in the right upper lobe. A few post-inflammatory lesions in both lungs. Partial arteriosclerosis.

3. Possible hemangioma in the liver; please confirm with contrast-enhanced MRI. Gallbladder bile concentration.

4. Chronic inflammatory changes in the gastric antrum; please confirm with endoscopy.

5. Degenerative changes in the spine; L3/4 intervertebral disc bulge. Widespread increased FDG metabolism in the medullary cavity throughout the body, suggesting possible reactive proliferative changes.

6. No obvious abnormalities were seen on cranial scintigraphy. A few chronic inflammations in the left maxillary sinus. Left upper alveolar ulceritis.

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.
