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 scan showed: Brain morphology and structure were normal, with punctate, slightly low-density shadows in the deep brain regions; FDG metabolism was normal.
The ventricles, sulci, fissures, and cisterns were widened, but local density and FDG uptake were normal; midline shift was not observed.
The eyeballs were symmetrical bilaterally, with no obvious abnormalities.
The maxillary sinus mucosa was thickened bilaterally, but the mucosa of the remaining paranasal sinuses was not thickened, and the sinus walls were intact.
The nasal septum was deviated, but the nasopharyngeal wall was not thickened; 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 bilateral parapharyngeal spaces were clear; FDG uptake was normal.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The oropharynx and laryngopharynx were normal in morphology and structure.
Thyroid gland is normal in shape and size, with uneven density.
A low-density nodule, approximately 1.8 cm in diameter, is present in the right lobe, showing increased FDG uptake (SUVmax = 3.6).
No enlarged lymph nodes are seen in the bilateral deep cervical spaces or submandibular region.
Increased lung markings are present bilaterally.
Multiple solid nodules with clear borders are present in both lungs, the largest approximately 0.4 cm in diameter, with no abnormal FDG uptake.
Scattered linear lesions are also present bilaterally, with no abnormal FDG uptake.
No pleural thickening is observed bilaterally, and there is no pleural effusion or pneumothorax bilaterally.
Multiple lymph nodes are seen in the right hilum, pretracheal space, para-aortic arch, aortopulmonary window, and subcarinal region, the largest located in the right hilum, with a short diameter of approximately 1.0 cm, showing increased FDG uptake (SUVmax = 6.5).
The cardiac silhouette is normal.
Calcification of some arterial walls (including coronary arteries) is present.
A port-a-cath has been inserted in the right anterior chest wall.
No esophageal dilation, no obvious thickening or mass in the esophageal wall, and no increased FDG uptake.
No obvious abnormalities in liver shape and size, smooth liver margins, no widening of the hepatic fissure, and a dense nodule in the right posterior lobe of the liver, approximately 0.4 cm in diameter, with no abnormal FDG uptake.
No obvious widening of the main portal vein, and no dilation of intrahepatic or extrahepatic bile ducts.
No abnormalities in gallbladder shape and size, no thickening of the gallbladder wall, and no abnormalities in local FDG uptake.
Slight atrophy of the pancreas, no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormalities in FDG uptake.
No abnormalities in spleen shape, size, density, or FDG uptake.
Numerous exudative shadows around both kidneys, no obvious abnormal density shadows in the parenchyma, no widening of the renal pelvis, calyces, or ureter, and no obvious abnormalities in FDG uptake.
Bilateral adrenal gland imaging showed no obvious abnormalities.
The stomach was poorly distended, with thickening of the cardia, part of the gastric body, and antrum walls, and increased FDG uptake (SUVmax = 3.5).
Following colorectal cancer treatment, a significant amount of residual contents was observed in the intestinal tract; no obvious space-occupying lesions were seen, and FDG metabolism was normal.
Dense suture shadows were seen in the distal rectum, with no thickening of the surrounding intestinal wall, and FDG metabolism was normal.
The prostate was full, with punctate dense shadows inside; FDG uptake was not abnormally increased.
A small amount of fluid was observed in the tunica vaginalis of the left testis.
The bladder was poorly distended, with no obvious positive stones.
No enlarged lymph nodes were seen in the abdomen or pelvis; small retroperitoneal lymph nodes were visible, the largest with a short diameter of approximately 0.4 cm; FDG metabolism was normal.
No significant fluid accumulation was seen in the abdominal or pelvic cavities.
Decreased bone density throughout the body, normal spinal alignment, marginal osteophyte formation at some vertebral bodies, and L4/5 disc herniation.
Patchy FDG uptake is observed in the left shoulder and left hip periarthritis, with SUVmax=3.0.
No abnormalities were found in bone marrow FDG metabolism.

Impression

1. After treatment for colorectal cancer, no obvious space-occupying lesions were found in the intestinal tract, and FDG metabolism was normal, suggesting suppressed tumor activity. Colonoscopy follow-up is recommended. Post-hemorrhoidectomy changes.

2. Chronic inflammatory micronodules in both lungs are highly probable; CT follow-up is recommended to rule out other possibilities. A few post-inflammatory lesions in both lungs. Reactive hyperplasia of the right hilar and mediastinal lymph nodes. Calcification of some arterial walls (including coronary arteries).

3. Calcification in the right lobe of the liver. Benign prostatic hyperplasia with calcification. Small amount of hydrocele in the left testis. Possible reactive hyperplasia of retroperitoneal lymph nodes.

4. Possible chronic inflammatory changes in the gastric wall; please follow up with endoscopy.

5. Osteoporosis, degenerative changes in the spine, L4/5 disc herniation. Inflammation of the left shoulder and left hip.

6. A low-density nodule in the right lobe of the thyroid gland with elevated FDG metabolism suggests a possible adenoma; please have a follow-up ultrasound examination.

7. A lacunar infarct in the deep brain region of an elderly patient; please have an MRI examination.

8. Chronic inflammation of both maxillary sinuses.

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.
