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: Normal brain morphology and structure; no abnormal density shadows were seen in the brain parenchyma; no significant abnormalities were observed in FDG uptake.
Enlargement of the ventricles, sulci, fissures, and cisterns was observed; the ventricles were symmetrical bilaterally, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed; the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; no abnormalities were observed in FDG uptake; the pharyngeal recesses were symmetrical bilaterally; there was no narrowing of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the parapharyngeal spaces were clear bilaterally, and no abnormalities were observed in FDG uptake.
The palatine tonsils showed physiological uptake bilaterally.
The laryngopharynx was normal in morphology and structure.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The thyroid gland was normal in morphology and size, with uniform density; no abnormalities were observed in FDG uptake.
No enlarged lymph nodes were observed bilaterally in the neck; no abnormalities in FDG metabolism were observed.
Increased translucency of both lungs, with multiple air-filled cystic cavities; an irregular nodule measuring approximately 2.0 1.8 cm is seen in the apical segment of the right upper lobe, with lobulated and spiculated margins, showing increased FDG metabolism (SUVmax = 12.6); several miliary nodules are seen in both lungs, with no abnormal FDG metabolism.
Linear lesions and calcifications are also seen in both lungs, with no abnormal FDG uptake.
No pleural thickening is observed bilaterally, and there is no pleural effusion or pneumothorax.
No significantly enlarged lymph nodes are seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette is normal.
Calcification is present in some arterial walls (including the coronary arteries).
The esophagus is not dilated, and the wall is not significantly thickened or swollen; FDG uptake is not increased.
The liver's shape and size are normal, with smooth borders and no widening of the hepatic fissure; multiple cystic lesions are seen within the liver, the largest being approximately 1.2 cm in length, with absent FDG uptake.
The main portal vein is not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts is observed.
The gallbladder showed no abnormalities in shape or size, and the gallbladder wall was not thickened; local FDG uptake was normal.
A 1.4*2.0cm cystic low-density lesion was seen in the head and neck of the pancreas; FDG uptake was not significantly abnormal.
The main pancreatic duct was not widened.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size; no significant abnormal density shadows were seen in the parenchyma; the renal pelvis, calyces, and ureters were not widened; FDG uptake was normal.
Bilateral adrenal glands showed no significant abnormalities on contrast.
The stomach was poorly distended; the stomach wall was not significantly thickened; FDG uptake was normal.
The intestines were poorly distended; the intestinal wall was not significantly thickened or lumped; FDG uptake was physiological.
The prostate was normal in size and density; FDG uptake was not abnormally increased.
The bladder was generally full; no obvious positive stones were seen.
Bilateral hydrocele was present.
No enlarged lymph nodes were seen in the abdominal cavity, pelvis, or retroperitoneal region; FDG metabolism was normal.
No obvious fluid accumulation was observed in the abdomen or pelvis.
The spinal alignment was normal, with some vertebral body margin osteophytes, and calcification of some anterior longitudinal ligament, nuchal ligament, and supraspinous ligament.
L4/5 and L5/S1 intervertebral disc bulges were observed, but FDG uptake was normal.
No abnormal FDG metabolism was observed in the entire skeleton.
A fat density foci with a long diameter of approximately 1.4 cm were observed in the right hip bone, but FDG uptake was normal.

Impression

1. a. Irregular nodule in the apical segment of the right upper lobe, with elevated FDG metabolism, suggestive of peripheral lung cancer; further clinical pathology is recommended. b. Several miliary chronic inflammatory nodules in both lungs. A few old lesions in both lungs. Emphysema in both lungs. Calcification of some arterial walls (including coronary arteries).

2. Cystic mass in the head and neck of the pancreas, cystadenoma to be ruled out; further examination with contrast-enhanced MRI is recommended. Multiple cysts in the liver. Bilateral hydrocele.

3. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulge. Fat deposition in the right hip bone.

4. Age-related brain 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.
