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: Multiple slightly high-density nodules of varying sizes were observed in the brain, the largest being approximately 1.0 0.9 cm in the right insula.
FDG metabolism was increased (SUVmax = 9.7), and a ring-shaped edema zone was observed around the nodules.
No widening of the ventricles, sulci, fissures, or cisterns was observed.
The ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical and showed no obvious 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, and there was no stenosis of the Eustachian tube openings.
The infratemporal and pterygopalatine fossae were structurally normal, and the parapharyngeal spaces were clear 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 morphology and structure of the laryngopharynx are normal.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes are seen in the bilateral deep cervical spaces or submandibular region.
An irregular mass measuring approximately 3.8 4.0 cm is seen in the anterior segment of the right upper lobe, closely adjacent to the horizontal fissure.
The mass has lobulated and spiculated margins, with increased FDG metabolism (SUVmax = 15.9).
Adjacent bronchus is obstructed, surrounded by patchy, indistinct shadows.
Multiple solid micronodules are seen in both lungs, with a long diameter of approximately 0.2?.4 cm and clear borders; FDG uptake is normal.
Patchy and strip-like areas of increased density are also seen in both lungs; FDG metabolism is normal.
A small amount of pleural effusion is present on the right side.
Multiple enlarged lymph nodes were observed in the right hilum, pretracheal space, para-aortic arch, aortic window, subcarinal region, and right supraclavicular fossa.
The largest lymph node had a short diameter of approximately 1.5 cm.
FDG metabolism was increased, with SUVmax = 5.9.
The cardiac silhouette was normal.
Calcification was observed in some arterial walls (including the coronary arteries).
The esophagus was not dilated, and the wall showed no significant thickening or mass; FDG uptake was not increased.
The liver's shape and size were normal, with smooth borders and no widening of the hepatic fissure.
Plain CT scan showed no abnormal density shadows in the liver parenchyma, and 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's shape and size were normal, with punctate dense shadows within the gallbladder lumen; FDG metabolism was normal.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct is not widened, and FDG uptake is not significantly abnormal.
The spleen is normal in shape, size, density, and FDG uptake.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is not significantly abnormal.
Both adrenal glands are slightly thickened, but FDG uptake is not abnormal.
The stomach is poorly distended, with no obvious thickening of the stomach wall, and FDG uptake is not significantly abnormal.
The intestines are poorly distended, with no obvious thickening or mass in the intestinal wall, and FDG uptake is physiological.
The prostate is normal in shape and size, with uniform density, and no abnormal FDG metabolism is observed.
The bladder is generally full, with no obvious positive stones.
No enlarged lymph nodes are seen in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No obvious fluid accumulation was observed in the abdomen or pelvis.
The spinal alignment was normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulges.
Nuchal ligament calcification was present.
Subcutaneous calcifications were present in both buttocks.
Increased bone density was observed on the iliac bone surfaces of both sacroiliac joints, but FDG uptake was normal.
Systemic bone marrow FDG metabolism was normal.

Impression

1. a. Space-occupying lesion in the right upper lobe of the lung, with increased FDG metabolism, suggestive of lung cancer with obstructive changes. b. Metastasis to the right hilar, mediastinal, and right supraclavicular fossa lymph nodes. Multiple small solid nodules in both lungs, suggesting possible metastasis; follow-up examination for comparison is recommended. c. Scattered inflammation in the remaining lungs. Small amount of pleural effusion in the right side. Calcification of some arterial walls (including coronary arteries).

2. Multiple intracranial nodules with increased FDG metabolism, highly suggestive of metastatic tumors.

3. Gallstones. Mild bilateral adrenal hyperplasia.

4. Spinal degenerative changes. L4/5 and L5/S1 intervertebral disc bulges. Bilateral sacroiliac joint degeneration. Subcutaneous calcifications in both buttocks.

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.
