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, and resting, a whole-body PET/CT scan was performed.
The whole-body scan showed: Multiple nodules of varying sizes with smooth margins were observed intracranially.
The largest was located at the right occipitotemporal junction, with a long axis of approximately 1.9 cm.
FDG uptake was increased (SUVmax = 7.8), and low-density edema was observed around it.
Nodular FDG uptake was also observed in the sellar region (SUVmax = 5.1).
Some ventricles, sulci, fissures, and cisterns were widened, with significant enlargement of the cisterna magna.
The ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical and showed no obvious abnormalities.
The ethmoid and maxillary sinuses showed thickening of the mucosa, but the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed, and FDG uptake was normal.
The bilateral pharyngeal recesses were symmetrical, and there was no stenosis of the Eustachian tube openings.
The infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear, with no abnormal FDG uptake.
No abnormal FDG uptake was observed in the oropharynx and laryngopharynx.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The thyroid gland showed uneven density; a slightly low-density nodule with a long diameter of approximately 0.8 cm was observed in the right lobe, with partially indistinct borders and increased FDG uptake (SUVmax = 2.5).
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, or submental region, and FDG metabolism was normal.
A soft tissue mass measuring approximately 4.5 2.7 cm was observed at the bronchial opening in the right upper lobe.
The mass had indistinct borders, slightly rough edges, and relatively uniform density.
The corresponding apical segment of the upper lobe bronchus was involved and truncated.
FDG uptake was increased (SUVmax = 8.6).
Scattered punctate and strip-shaped high-density shadows were visible distally, some containing air accumulating within them.
FDG uptake was increased (SUVmax = 3.4).
A small air-filled cyst was observed in each of the right upper and lower lobes.
Scattered linear shadows were seen in both lungs, with no abnormal FDG uptake.
There was no pleural effusion or air accumulating bilaterally.
Multiple lymph nodes were observed in the right hilum and mediastinum (right paratracheal, posterior to the vena cava), the largest with a short diameter of approximately 1.9 cm.
FDG uptake was increased (SUVmax = 6.5).
The cardiac silhouette was normal.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissure.
Multiple low-density nodules with indistinct borders were observed in the right lobe of the liver, showing increased FDG uptake, the largest measuring approximately 1.9 1.2 cm, with an SUVmax of 7.0.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder was smaller than normal, with thickened and rough walls.
A small, round, high-density shadow was visible within the lumen, but local FDG uptake was normal.
The pancreas was normal in shape, with no obvious 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 showed no abnormal density shadows in the parenchyma, and FDG uptake was normal.
Multiple punctate high-density shadows were observed in both renal calyces.
The right adrenal gland showed no obvious abnormalities on contrast.
The left adrenal gland shows nodular thickening with relatively clear borders, approximately 2.3 1.1 cm, with increased FDG uptake (SUVmax = 6.4).
Several round or oval nodules are seen in the bilateral retrorenal spaces, the largest being approximately 1.1 0.8 cm on the right side, with increased FDG uptake (SUVmax = 5.5).
The esophagus is not dilated, and the wall is not significantly thickened or swollen; FDG uptake is not increased.
Gastric distension is poor, with localized increased FDG uptake on the greater curvature of the stomach wall (SUVmax = 3.1).
Intestinal distension is poor, and the intestinal wall is not significantly thickened or swollen; FDG uptake is physiological.
The prostate is enlarged with punctate calcifications; FDG uptake is not abnormally increased.
The bladder is adequately distended, and no obvious positive stones are seen.
No significant fluid accumulation is seen in the abdomen or pelvis.
Bone destruction was observed in the left parietal bone, with surrounding soft tissue mass.
FDG metabolism was elevated, with SUVmax = 6.9.
Bone destruction was also observed in the left humerus, right scapula, multiple ribs bilaterally, multiple vertebrae and some appendages of the spine, bones of the pelvis, and both femurs.
FDG uptake was elevated, with SUVmax = 10.3.
The spinal alignment was normal, with Schmorl's nodes observed in some thoracic and lumbar vertebrae.
Osteophytes were present at the marginal vertebrae of some vertebrae.
Sacral canal enlargement with cystic density shadows was observed at the S1-2 vertebral level, and L5/S1 disc herniation was present.

Impression

1. a. Soft tissue mass at the bronchial opening in the right upper lobe of the lung, with increased FDG metabolism, suggestive of lung cancer, accompanied by distal peripheral obstructive changes; please correlate with clinicopathology; multiple lymph node metastases in the right hilum and mediastinum. b. Multiple intracranial metastases, sellar region mass, pituitary adenoma to be ruled out; enhanced MRI follow-up recommended. Elderly brain, large occipital region and cisterna magnum. c. Multiple metastases in the right lobe of the liver; bilateral retrorenal space metastases or lymph node metastases; left adrenal metastasis; multiple bone metastases throughout the body.

2. Localized emphysema in the upper and lower lobes of the right lung. A few fibrotic lesions in both lungs.

3. Gallstones and chronic cholecystitis. Multiple kidney stones in both kidneys. Benign prostatic hyperplasia with calcification.

4. Localized hypermetabolic FDG lesions on the greater curvature of the stomach wall, suggestive of possible inflammatory changes; follow-up gastroscopy is recommended to rule out malignancy.

5. Spinal osteophyte formation. Schmorl's nodes in some thoracic and lumbar vertebrae. Sacral canal cyst. L5/S1 disc herniation.

6. Uneven thyroid density, low-density nodule in the right lobe with increased FDG metabolism, suggestive of adenoma; follow-up ultrasound is recommended.

7. Bilateral ethmoid and maxillary sinusitis.

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.
