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 scan showed: a few punctate low-density shadows in the deep bilateral cerebral regions; no abnormal density shadows were seen in the remaining brain parenchyma, and FDG uptake was normal.
The ventricles, sulci, fissures, and cisterns were widened, with symmetrical bilateral ventricles and no midline shift.
The eyeballs were symmetrical bilaterally, with no obvious abnormalities.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasopharyngeal wall showed no thickening, and 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, with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake.
The laryngopharynx showed no abnormalities in morphology or structure.
The parotid and submandibular glands showed no abnormal density shadows bilaterally.
The thyroid gland was normal in shape and size, with uniform density, and FDG uptake was normal.
No enlarged lymph nodes were seen bilaterally in the neck, and FDG metabolism was normal.
An irregular mass measuring approximately 8.1 7.9 cm was observed in the left upper lobe, adjacent to the mediastinum.
FDG metabolism was elevated, with an SUVmax of 23.1.
The mass was poorly demarcated from adjacent major vessels and the pericardium.
Scattered patchy shadows were observed around the mass.
Increased translucency and thickened interlobular septa were observed in both lungs.
Multiple air-filled cystic cavities were seen in the subpleural region of both lungs.
Multiple scattered punctate and linear lesions were observed in both lungs, with normal FDG metabolism.
Moderate pleural effusion was present in the left side.
Slight pericardial thickening was observed.
Several slightly enlarged lymph nodes were observed in the bilateral hilar regions, pretracheal spaces, para-aortic arch, aortopulmonary window, and below the carina, the largest being approximately 1.0 cm in short diameter, with elevated FDG metabolism and an SUVmax of 3.6.
Multiple soft tissue nodules were observed in the left lower 6th-10th intercostal spaces, the largest being approximately 1.2 cm in long diameter, with elevated FDG metabolism and an SUVmax of 9.6.
The cardiac silhouette was normal.
Calcification of some arterial walls (including the coronary arteries) was observed.
The esophagus showed no dilation, thickening or mass in the esophageal wall, and no increased FDG uptake.
The liver was normal in shape and size, with smooth borders, no widening of the hepatic fissure, and no abnormal density shadows in the liver parenchyma on plain CT scan; FDG uptake was normal.
The main portal vein was not significantly widened, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder was normal in shape and size, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormal FDG uptake.
The spleen was normal in shape, size, density, and FDG uptake.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma; no widening of the renal pelvis, calyces, or ureters was observed, and FDG uptake was normal.
Bilateral adrenal glands showed no obvious abnormalities on contrast.
The stomach was poorly distended, with no obvious thickening of the gastric wall and no obvious abnormal FDG uptake.
The intestines were not well-filled, but no obvious thickening or masses were observed in the intestinal wall; FDG uptake was normal.
An air-filled cavity was observed in the descending duodenum; FDG metabolism was normal.
The prostate was of normal size and uniform density; FDG uptake was not abnormally increased.
The bladder was generally full, and no obvious positive stones were observed.
No enlarged lymph nodes were observed in the abdominal cavity, pelvis, or retroperitoneal region; FDG metabolism was normal.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulges; FDG uptake was normal.
No abnormal FDG metabolism was observed in the entire skeletal system.

Impression

1. a. A space-occupying lesion in the left upper lobe, adjacent to the mediastinum, with increased FDG metabolism, consistent with lung cancer with obstructive changes, invading adjacent major blood vessels and the pericardium. b. Multiple soft tissue nodules in the left lower 6th-10th intercostal spaces, with normal FDG metabolism, suggestive of metastatic tumors. c. Moderate pleural effusion in the left side. Slight pericardial thickening. Reactive hyperplasia of the hilar and mediastinal lymph nodes is highly probable, with partial metastasis to be ruled out. d. Interstitial changes in both lungs with multiple scattered chronic inflammations and old lesions. Emphysema with bullae in both lungs. Calcification of some arterial walls (including coronary arteries).

2. Duodenal diverticulum in the descending part.

3. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulges.

4. A few ischemic lesions in the deep bilateral brain, senile cerebral changes.

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.
