Whole-body 18F-FDG PET/CT scan in a patient with Lung 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 in FDG uptake were observed.
No widening was observed in the ventricles, sulci, fissures, or cisterns; local density and FDG uptake were normal; and there was no midline shift.
The bilateral eyeballs showed normal morphology and contours; retrobulbar structures were clear; the bilateral optic nerves were symmetrical; and FDG uptake was normal.
The right maxillary sinus mucosa showed slight thickening, but the sinus wall was intact; FDG uptake was normal.
The nasopharyngeal wall showed no thickening; FDG uptake was normal; the bilateral pharyngeal recesses were symmetrical; there was no stenosis of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the bilateral parapharyngeal spaces were clear; and FDG uptake was normal.
The bilateral oropharyngeal lateral walls were full; FDG uptake was increased (SUVmax = 6).
The laryngopharynx showed no abnormalities in morphology and structure.
The thyroid gland was normal in shape and size, with uniform density; and FDG uptake was normal.
An irregular soft tissue density mass measuring approximately 4.6*4.9cm was observed in the right upper deep cervical space, with increased FDG uptake (SUVmax = 22.2).
The adjacent submandibular gland was enlarged, but the boundary between the mass and the lesion was indistinct.
No significantly enlarged lymph nodes were observed in the left deep cervical space, submandibular region, or submental region; FDG uptake was normal.
Two mixed ground-glass opacities were observed in the apical segment of the right upper lobe and the posterior segment of the right lower lobe.
The larger one, located in the right upper lobe, measured approximately 0.9*1.2cm, with several small blood vessels entering it; FDG uptake was slight (SUVmax = 1.6).
A small nodule, approximately 0.4cm in long diameter, was observed in the anterior segment of the right upper lobe; FDG uptake was normal.
Scattered fibrous bands were observed in both lungs; FDG uptake was normal.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
Multiple lymph nodes were observed in the bilateral hilar and mediastinal regions, the largest approximately 0.6cm in short diameter; some showed increased FDG uptake (SUVmax = 5.5).
Cardiac imaging was normal.
Calcification was observed in some arterial walls (including the coronary arteries).
The esophagus showed no dilation, no significant thickening of the wall, and no increased FDG uptake.
Bilateral mammary fibroadenomas were normal, with no abnormal density shadows and no abnormal FDG uptake.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
Multiple cystic lesions were present in the liver, the largest approximately 0.5 cm in diameter, with absent FDG uptake.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts.
Following cholecystectomy, the common bile duct was widened, with the lower segment appearing as a cup-shaped truncation; no abnormal FDG uptake was observed.
The pancreas showed no abnormalities in shape or size, with no significant abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, no abnormal FDG uptake, and clear peripancreatic spaces.
The spleen showed no abnormalities in shape or size, density, or FDG uptake.
Both kidneys showed no abnormalities in shape or size, with no significant abnormal density shadows in the renal parenchyma and no significant abnormal FDG uptake.
No widening of the renal pelvis, calyces, or ureters was observed bilaterally, and no positive calculi were seen.
The bilateral adrenal glands showed no abnormalities in morphology or density, and FDG uptake was normal.
Gastric distension was poor, but the gastric wall showed no significant thickening, and FDG uptake was normal.
The ascending colon hepatic flexure showed thickening of the intestinal wall, with nodular protrusions into the lumen, and increased FDG uptake (SUVmax = 10.0).
Delayed scan showed persistently increased FDG uptake (SUVmax = 11.8).
In the elderly patient, no abnormal density shadows were seen in the uterus or cervix, and FDG uptake was normal.
No abnormal density was seen in the bilateral adnexa, and FDG uptake was normal.
The bladder showed poor distension, but no positive calculi were seen.
No enlarged lymph nodes were seen in the abdominal cavity, pelvis, or retroperitoneal region, and FDG uptake was normal.
No significant fluid accumulation was seen in the abdominal or pelvic cavities.
Osteoporosis was present.
The spinal alignment was normal, with some vertebral body margins and facet joint processes showing osteophyte formation, and mild L5/S1 intervertebral disc bulging.
No abnormalities were observed in FDG uptake.

Impression

1. a. An irregular soft tissue density mass with increased FDG metabolism in the right upper deep cervical space, suggestive of malignancy, more likely primary than metastatic. The lesion involves the adjacent submandibular gland; please correlate with clinical findings and tissue biopsy. b. Full morphology of the bilateral oropharyngeal lateral walls with increased FDG uptake, suggesting possible chronic inflammation or physiological changes; specialist examination recommended.

2. a. Mixed ground-glass nodules with slight FDG uptake in the apical segment of the right upper lobe and the posterior segment of the right lower lobe, highly suggestive of invasive adenocarcinoma (AIC). b. Small inflammatory nodules in the right upper lobe; please follow up with CT scan. Scattered chronic inflammation and remnants in both lungs. Reactive hyperplasia of bilateral hilar and mediastinal lymph nodes. Partial arteriosclerosis (including coronary arteries).

3. Thickening of the intestinal wall in the hepatic flexure of the ascending colon, protruding into the lumen in a nodular manner with increased FDG metabolism, suggesting possible polyps; colonoscopy recommended to rule out malignancy.

4. Post-cholecystectomy, the common bile duct is widened, and the lower segment appears to be cup-shaped. FDG showed no abnormal uptake, suggesting possible post-operative changes. MRI is recommended to rule out space-occupying lesions. Multiple small cysts in the liver.

5. Osteoporosis. Degenerative changes in the spine. Mild L5/S1 intervertebral disc bulge.

6. Cranial scintigraphy showed no obvious abnormalities. A small amount of chronic inflammation in the right maxillary sinus.

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.
