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, and resting, a whole-body PET/CT scan was performed.
The whole-body tomographic images showed:The brain morphology and structure were normal, with no abnormal density shadows in the brain parenchyma, and no significant abnormalities 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, with no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed, 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 abnormalities in FDG uptake.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The oropharynx and laryngopharynx were normal in morphology and structure.
The thyroid gland was normal in morphology and size, with slightly uneven density, and no abnormalities in FDG uptake.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
A port-a-cath was inserted in the right clavicular region.
Lung markings were clear bilaterally.
Solid nodules with clear borders were observed in the posterior segment of the right upper lobe and the posterior segment of the right lower lobe, the largest being approximately 0.4 cm in diameter.
No abnormal FDG uptake was observed.
A few linear lesions were observed in the right lower lobe, with no abnormal FDG uptake.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal.
Partial arteriosclerosis was observed.
The mammary glands were dense bilaterally.
Calcification was observed in the left breast, with no abnormal FDG metabolism.
The esophagus was not dilated, and the esophageal wall was not significantly thickened or lumped.
No increased FDG uptake was observed.
Following resection of liver metastases, the left lobe of the liver was partially absent, with linear dense shadows visible at the liver margin.
No significant space-occupying lesions were observed in the remaining liver area, and FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape or size, and the gallbladder wall showed no thickening; local FDG uptake was normal.
The pancreas was normal in shape, with no significant 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 significant abnormal density shadows in the parenchyma; the renal pelvis, calyces, and ureters were not widened, and FDG uptake was normal.
Bilateral adrenal gland contrast imaging showed no significant abnormalities.
Stomach distension is poor, with slight thickening of some gastric walls.
FDG uptake is increased, SUVmax = 1.9.
Post-colon cancer surgery, a large amount of residual contents are seen in the intestinal lumen.
An anastomosis is seen in the sigmoid colon.
No thickening of the surrounding intestinal walls is observed.
FDG metabolism is normal.
The uterine margins are not smooth, but no abnormal density shadows are seen.
FDG uptake is normal.
No obvious abnormalities are seen in the bilateral adnexa.
The bladder is poorly distended, but no obvious positive stones are seen.
No enlarged lymph nodes are seen in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No obvious fluid accumulation is seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with mild osteophyte formation at the margins of some vertebral bodies.
L4/5 and L5/S1 intervertebral disc bulges.
Systemic bone marrow FDG metabolism is normal.

Impression

1. a. Postoperative changes after colon cancer surgery; no signs of tumor recurrence were observed in the surgical area. Colonoscopy follow-up is recommended. b. Postoperative changes after resection of liver metastases; no significant space-occupying lesions were observed in the remaining liver, and FDG metabolism was normal.

2. Chronic inflammatory micronodules in the right lung; CT follow-up is recommended. A few post-inflammatory remnants in the right lung. Partial arteriosclerosis.

3. Bilateral breast hyperplasia; calcification in the left breast; ultrasound follow-up is recommended.

4. Chronic gastritis; please combine with endoscopic follow-up.

5. Mild vertebral osteophyte formation. L4/5 and L5/S1 intervertebral disc bulges.

6. No significant abnormalities were found on cranial 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.
