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

Under fasting conditions, an intravenous injection of 18F-FDG was administered, followed by rest.
Whole-body PET/CT imaging revealed: Normal brain morphology and structure, with calcification of the falx cerebri and punctate, slightly low-density shadows in the deep brain regions.
FDG uptake showed no significant abnormalities.
The ventricles, sulci, fissures, and cisterns were slightly widened; 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.
No thickening of the nasopharyngeal wall was observed, and FDG uptake was normal.
The pharyngeal recesses were symmetrical bilaterally, and there was no stenosis of the Eustachian tube openings.
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.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
The thyroid gland is normal in shape and size, but its density is somewhat uneven.
FDG uptake is not abnormal.
No enlarged lymph nodes are seen in the bilateral deep cervical spaces or submandibular region.
Both lungs show clear lung markings.
An irregular soft tissue mass, approximately 4.1*3.2cm in size, is located in the anterior segment of the right upper lobe near the hilum, with indistinct borders and uneven density.
FDG uptake is increased (SUVmax = 17.9).
An irregular patchy shadow, approximately 3.9*2.7cm in size, is also present in the anterior segment of the right upper lobe, with indistinct borders and increased FDG uptake (SUVmax = 11.1).
A bronchial transection is present in the anterior segment of the right upper lobe.
Multiple hazy patchy shadows and large areas of increased density are seen in the right upper lobe, with increased FDG uptake (SUVmax = 11.1).
Multiple small solid nodules are present in the remaining lungs, the largest being approximately 0.4cm in diameter.
FDG uptake is normal.
Calcifications are present in both lower lobes.
Scattered linear lesions are present in both lungs, with normal FDG uptake.
Right pleural thickening is present, but there is no pleural effusion or pneumothorax.
Multiple enlarged lymph nodes were observed in the right hilum, pretracheal space, aortic window, subcarinal region, and right cardiophrenic angle.
The largest lymph node had a short diameter of approximately 3.0 cm, with increased FDG uptake (SUVmax = 20.9).
The cardiac silhouette was normal.
Calcification was observed in some arterial walls (including the coronary arteries).
The esophagus showed no dilation, wall thickening, or masses, and FDG uptake was not increased.
The liver showed no significant abnormalities in morphology or size, with smooth borders, no widening of the hepatic fissures, and decreased liver density (CT value: 40 HU).
Diffusely distributed low-density nodules of varying sizes were observed in the liver, some fused into patches.
The largest nodule had a long diameter of approximately 2.7 cm, with increased FDG uptake (SUVmax = 21.0).
The main portal vein showed no significant widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
Gallbladder: No abnormalities in shape or size.
Gallbladder wall is thickened, with dense nodules within the gallbladder, approximately 1.5 cm in long diameter.
Local FDG uptake is normal.
Pancreas: Normal shape.
No obvious abnormal density shadows are seen in the parenchyma.
The main pancreatic duct is not widened.
FDG uptake is normal.
Spleen: No abnormalities in shape, size, density, or FDG uptake.
Kidneys: Normal shape and size.
No obvious abnormal density shadows are seen in the parenchyma.
The renal pelvis, calyces, and ureters are not widened.
FDG uptake is normal.
Bilateral adrenal glands: No obvious abnormalities are seen on contrast.
Stomach: Poor distension.
Slight thickening of the antral wall.
Mildly increased FDG uptake (SUVmax = 2.2).
Intestinal distension: Insufficient.
Intestinal uptake is physiological.
Prostate: Normal size.
Calcifications are seen within the prostate.
FDG uptake is normal.
The bladder was poorly filled, with increased density shadows visible inside.
Multiple enlarged lymph nodes were observed in the hepatogastric space and retroperitoneum, the largest measuring approximately 1.4 cm in short diameter, showing increased FDG uptake (SUVmax = 21.5).
Multiple bone destruction with increased FDG uptake was observed in the right upper humerus, bilateral scapulae, multiple ribs, multiple vertebrae and their appendages in the spine, bones of the pelvis, and the medullary canal of the left upper femur (SUVmax = 14.8).
The spinal alignment was normal, with osteophyte formation at the margins of some vertebral bodies, and a bulging L5/S1 intervertebral disc with pneumoconiosis and degeneration.

Impression

1. a. Space-occupying lesion in the right upper lobe with increased FDG metabolism, suggestive of lung cancer with obstructive inflammation. b. Multiple lymph node metastases in the right hilum, mediastinum, right cardiophrenic angle, hepatogastric space, and retroperitoneum. c. Multiple liver metastases. Multiple bone metastases throughout the body (see description for details).

2. Infection in the right upper lobe. Chronic inflammatory micronodules in both lungs. Calcifications in the lower lobes of both lungs, scattered post-inflammatory remnants in both lungs. Right pleural thickening. Calcification of some arterial walls (including coronary arteries).

3. Fatty liver. Chronic cholecystitis, gallstones. Residual contrast agent in the cystostomy. Calcifications in the prostate.

4. Chronic inflammatory changes in the gastric antrum.

5. Degenerative changes in the spine, L5/S1 intervertebral disc bulge with pneumoconiosis and degeneration.

6. Mild age-related brain changes, calcifications in the falx cerebri, and deep lacunar infarcts.

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.
