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 scan 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.
The eyeballs were symmetrical bilaterally, with no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
The nasal septum was slightly deviated, but the nasopharyngeal wall was not thickened, and FDG uptake was normal.
The pharyngeal recesses were symmetrical bilaterally, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the parapharyngeal spaces were clear bilaterally, with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake bilaterally.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The laryngopharynx morphology and structure were normal.
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.
Multiple nodules, patchy shadows, and calcifications are present in the apical segment of the right upper lobe and the posterior segment of the left lower lobe, with increased FDG uptake (SUVmax = 2.5).
Multiple solid nodules are present in both lungs, the largest being approximately 0.4 cm in diameter; FDG uptake is normal.
Multiple air-filled cavities are present in both lungs.
Scattered linear lesions are present in both lungs; FDG uptake is normal.
Pleural thickening is present bilaterally, with calcification on the left side.
There is no pleural effusion or pneumothorax bilaterally.
Small mediastinal lymph nodes are visible, the largest having a short diameter of approximately 0.8 cm; FDG uptake is normal.
Cardiac silhouette is normal.
Calcification is present in some arterial walls (including coronary arteries).
No esophageal dilation, no significant thickening or mass in the esophageal wall, and no increased FDG uptake.
No obvious abnormalities were observed in the liver's morphology and size; the liver margins were smooth, the hepatic fissures were not widened, and a small cystic lesion, approximately 0.5 cm in diameter, was present in the left lobe of the liver; FDG uptake was normal.
No significant widening of the main portal vein was observed, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
No abnormalities were observed in the gallbladder's morphology and size; the gallbladder wall was not thickened, and local FDG uptake was normal.
The pancreas was normal in morphology; a cystic lesion, approximately 1.5*1.1 cm in size, was present in the pancreatic tail; FDG metabolism was normal, the main pancreatic duct was not widened, and FDG uptake was not significantly abnormal.
No abnormalities were observed in the spleen's morphology, size, density, or FDG uptake.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows seen in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging shows no obvious abnormalities.
The stomach is poorly distended, with slight thickening of the walls of the cardia, part of the gastric body, and antrum, and mildly increased FDG uptake (SUVmax = 2.5).
Anal canal FDG uptake is increased (SUVmax = 5.2).
Irregular thickening of the descending colon wall is observed, with increased FDG uptake (SUVmax = 15.5), covering an area of approximately 3.5*2.6*3.3cm.
The intestinal lumen is narrowed, and the serosal surface is rough.
Irregular thickening of the ascending colon near the hepatic flexure is also observed, with increased FDG uptake (SUVmax = 9.0), covering an area of approximately 4.0*1.8*3.4cm.
The intestinal lumen is narrowed.
No significantly enlarged lymph nodes or effusion are observed in the abdominopelvic cavity.
The prostate is of normal size and uniform density, with no abnormally increased FDG uptake.
The left testis is located in the left inguinal region.
Bladder distension is poor, with no obvious positive stones observed.
The spinal alignment is normal, with some vertebral body margin osteophytes; L4-5 vertebral bodies are currently under internal metal fixation.
Patchy FDG uptake is observed bilaterally around the shoulders, with SUVmax = 2.2.
Systemic bone marrow FDG metabolism is normal.

Impression

1. Irregular thickening of the descending colon wall with increased FDG metabolism suggests colorectal cancer. Irregular thickening of the ascending colon wall near the hepatic flexure with increased FDG metabolism also suggests colorectal cancer.

2. a. Old lesions in the apical segment of the right upper lobe and the posterior segment of the left lower lobe. Chronic inflammatory micronodules in both lungs. Emphysema in both lungs, scattered post-inflammatory remnants in both lungs. b. Reactive hyperplasia of mediastinal lymph nodes. Pleural thickening bilaterally, with calcification on the left. Calcification of some arterial walls (including coronary arteries).

3. Small liver cysts. Cystic mass in the tail of the pancreas, likely a cyst, cystadenoma to be ruled out; enhanced MRI follow-up recommended. Left cryptorchidism.

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

5. Degenerative changes in the spine, postoperative changes after lumbar spine surgery. Bilateral frozen shoulder.

6. No obvious 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.
