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 scan showed: punctate low-density shadows in the deep bilateral brain regions; nodular low-density lesions with clear borders in the right basal ganglia; decreased white matter density around the ventricles; and no significant abnormalities in FDG uptake.
The ventricles, sulci, fissures, and cisterns were widened, with symmetrical bilateral ventricles and no midline shift.
Both eyes were symmetrical and without significant 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, 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 was normal in morphology and structure.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The thyroid gland is normal in shape, with several low-density nodules in both lobes, indistinct borders, and no abnormal FDG uptake.
Punctate calcifications are also seen in the right lobe.
No enlarged lymph nodes are seen bilaterally in the neck, and FDG metabolism is normal.
An irregular mass measuring approximately 3.4 3.2 cm is seen in the lingular segment of the left upper lobe, with increased FDG metabolism (SUVmax = 12.3).
Several solid micronodules, approximately 0.2-0.3 cm in long diameter, with clear borders, are seen bilaterally in both lungs, and FDG metabolism is normal.
Increased translucency is seen bilaterally, with a few linear and punctate foci, and FDG metabolism is normal.
No pleural thickening is seen bilaterally, and there is no pleural effusion or pneumothorax bilaterally.
One enlarged lymph node is seen in the left hilum and the main pulmonary artery window, the latter being slightly larger, with a short diameter of approximately 1.4 cm, and increased FDG metabolism (SUVmax = 9.7).
The cardiac silhouette is normal.
Calcification is present in some arterial walls (including the coronary arteries).
The esophagus showed no dilation, no significant thickening or mass in the esophageal wall, and no increased FDG uptake.
The liver showed no significant abnormalities in shape or size, with smooth borders, no widening of the hepatic fissure, and no significant abnormal density shadows in the liver parenchyma on plain CT scan; FDG uptake was normal.
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 or size, with slight thickening of the gallbladder wall and several small punctate dense shadows within the lumen; FDG metabolism was normal.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma; the main pancreatic duct was not widened; FDG uptake was normal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size, with no significant abnormal density shadows in the parenchyma; the renal pelvis, calyces, and ureters were not widened; FDG uptake was normal.
A soft tissue mass measuring approximately 4.8 3.0 cm was observed in the left adrenal gland, with increased FDG metabolism (SUVmax = 11.7).
No significant abnormalities were seen on the right adrenal gland.
The stomach was poorly distended, with slight thickening of the walls in parts of the gastric body and antrum, and mildly increased FDG uptake (SUVmax = 2.3).
The intestines were also poorly distended, with continuous FDG metabolism in parts of the colon and rectum (SUVmax = 4.6).
The prostate was of normal size and uniform density, with no abnormally increased FDG uptake.
The bladder was generally full, with no obvious positive stones.
An enlarged lymph node was observed anterior to the left of the abdominal aorta, the largest having a short diameter of approximately 1.3 cm, with increased FDG metabolism (SUVmax = 11.5).
No significant fluid accumulation was observed in the abdomen or pelvis.
The spinal alignment was normal, with some vertebral marginal osteophyte formation and L4/5 and L5/S1 intervertebral disc bulging, but no abnormal FDG uptake was observed.
No abnormal FDG metabolism was observed in the entire skeletal system.

Impression

1. a. A mass in the lingular segment of the left upper lobe of the lung, with increased FDG metabolism, suggestive of lung cancer. Left adrenal metastasis. b. Metastasis to the pulmonary artery window and the left anterior lymph nodes of the abdominal aorta. Left hilar lymph node metastasis is highly probable. c. Several small, solid, chronic inflammatory nodules in both lungs. Bilateral emphysema, a few chronic inflammations, and old lesions. Calcification of some arterial walls (including the coronary arteries). d. Softening lesions in the right basal ganglia region, bilateral deep cerebral ischemia, leukoencephalopathy, and age-related brain changes; no obvious space-occupying lesions seen intracranially. Enhanced intracranial MRI is recommended.

2. Slight thickening of the walls of part of the gastric body and antrum, with mildly increased FDG uptake, suggestive of chronic gastritis; increased FDG metabolism in part of the colon and rectum, suggestive of inflammatory or physiological uptake. Follow-up with gastroscopy and colonoscopy is recommended.

3. Chronic cholecystitis. Gallstones.

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

5. Several low-density nodules in both lobes of the thyroid gland, with calcification in the right lobe. FDG metabolism was normal. Nodular goiter is highly suspected, and ultrasound re-examination is recommended.

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.
