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

Under fasting conditions, an intravenous injection of 18F-FDG was administered, followed by rest.
Whole-body PET/CT imaging revealed the following: Brain morphology and structure were normal, with punctate low-density shadows in the deep cerebral regions bilaterally; FDG uptake was normal.
No widening was observed in the ventricles, sulci, fissures, or cisterns; local density and FDG uptake were normal; midline shift was normal.
The morphology and contours of both eyeballs were normal; retrobulbar structures were clear; optic nerves were symmetrical bilaterally; FDG uptake was normal.
No thickening was observed in the paranasal sinus mucosa; sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; no stenosis was observed in the bilateral pharyngeal recesses or Eustachian tube openings; the infratemporal fossa and pterygopalatine fossa structures were normal; bilateral parapharyngeal spaces were clear; FDG uptake was normal.
The bilateral palatine tonsils were full and showed physiological FDG uptake.
The morphology and structure of the laryngopharynx were normal.
No abnormal visualization was observed in the bilateral parotid and submandibular glands.
Thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
Small lymph nodes are seen in the bilateral deep cervical spaces, submandibular region, and submental region; FDG uptake is normal.
The thoracic cage is symmetrical, with the mediastinum and trachea in the midline.
A solid miliary nodule is seen in the lateral basal segment of the left lower lobe; a few linear shadows and patchy hazy shadows are seen in both lungs; FDG uptake is normal.
No pleural thickening is seen bilaterally; there is no pleural effusion or pneumothorax bilaterally.
Small lymph nodes are seen in the bilateral hilar regions and mediastinum; FDG uptake is normal.
The cardiac silhouette is normal; myocardial FDG uptake is normal.
Some arterial walls are calcified (including the coronary arteries).
No significant thickening or mass is seen in the esophageal wall; FDG uptake is normal.
Both breasts are normal in shape; several calcifications are seen in the right breast; FDG uptake is normal.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissure.
The liver parenchyma showed slightly decreased density, and multiple slightly low-density nodules were observed in the left lobe, the largest being approximately 1.9 cm in long diameter, with relatively clear borders.
FDG showed background uptake.
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 and size, with no thickening of the gallbladder wall, but patchy dense shadows were observed internally.
FDG uptake was normal.
The pancreas showed no abnormalities in shape, with no obvious abnormal density shadows in the parenchyma, and no widening of the main pancreatic duct.
FDG uptake was normal.
The spleen showed no abnormalities in shape and size, but a slightly low-density lesion measuring approximately 3.5*2.6 cm was observed internally, with relatively clear borders.
FDG showed background uptake.
The shape and size of both kidneys are normal, and no obvious abnormal density shadows are seen in the renal parenchyma.
FDG uptake is normal.
No widening of the renal pelvis, calyces, or ureters is observed, and no positive stones are seen.
The shape and density of both adrenal glands are normal, and FDG uptake is normal.
Gastric distension is poor, but FDG uptake is normal.
Post-colon cancer treatment: No thickening or obvious mass is seen in the intestinal wall at the surgical site anastomosis, and FDG uptake is normal.
Post-duodenal lesion treatment: No thickening of the intestinal wall is seen in the surgical site, the surrounding mesentery is slightly thickened, FDG uptake is increased, SUVmax=3.2.
No enlarged lymph nodes are seen in the abdomen, pelvis, or retroperitoneum.
No obvious effusion is seen in the abdomen or pelvis.
The uterus is shrunken, with no abnormal density shadows, and FDG uptake is normal.
No abnormal density is seen in the bilateral adnexa, and FDG uptake is normal.
The bladder is adequately full, and no positive stones or obvious masses were observed.
Scoliosis, osteophyte formation at the margins of some vertebral bodies, and T12/L1 disc herniation with pneumothorax are present.
FDG uptake of all bones is normal.

Impression

1. a. Post-colon cancer treatment: No abnormal FDG metabolic foci were observed in the surgical area. b. Post-duodenal lesion treatment: The mesentery around the surgical area was slightly thickened, and FDG metabolism was increased, suggesting possible post-operative changes. Tumor recurrence needs to be ruled out; close observation is recommended.

2. Chronic miliary nodules in the lateral basal segment of the left lower lobe, chronic inflammation and sequelae in both lungs. Reactive hyperplasia of the hilar and mediastinal lymph nodes in both lungs. Partial arteriosclerosis (including coronary arteries). Several calcifications in the right breast.

3. Mild fatty liver, hepatic hemangioma is highly probable; ultrasound follow-up is recommended. Gallstones. Slightly low-density lesions in the spleen, with FDG showing background uptake, suggesting a high probability of hemangioma; ultrasound follow-up is recommended.

4. Scoliosis with degenerative changes. T12/L1 disc herniation with pneumothorax and degeneration.

5. Bilateral deep lacunar infarcts.

6. Thyroid gland density is uneven; FDG metabolism is normal. Ultrasound follow-up is recommended. Bilateral cervical lymph node reactive hyperplasia.

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.
