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 images showed: Normal brain morphology and structure; no abnormal density shadows were seen in the brain parenchyma; no significant abnormalities in FDG uptake were observed.
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 significant abnormalities.
Bilateral ethmoid sinus mucosal thickening was observed, but the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; FDG uptake was normal; the pharyngeal recesses were symmetrical; there was no stenosis of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the bilateral parapharyngeal spaces were clear, and FDG uptake was normal.
Increased FDG metabolism was observed in the bilateral palatine tonsils and oropharynx (SUVmax = 8.6).
No abnormalities were observed in the morphology and structure of the laryngopharynx.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The thyroid gland was normal in shape and size, with uniform density; FDG uptake was normal.
No enlarged lymph nodes were observed bilaterally in the neck, and FDG metabolism was normal.
A pneumocystic cavity measuring approximately 1.3 2.7 2.2 cm was observed in the lateral basal segment of the right lower lobe, with thickened walls and lobulated margins; FDG metabolism was slightly elevated (SUVmax = 2.2).
Several miliary nodules were also observed in the right lung, with normal FDG metabolism.
The pleura was slightly thickened bilaterally, but there was no pleural effusion or pneumocystis.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal.
The esophagus was not dilated, and the wall was not significantly thickened or swollen; FDG uptake was normal.
The liver was normal in shape and size, with smooth borders and no widening of the hepatic fissure.
A cystic low-density lesion approximately 0.5 cm in long diameter was observed in the left lobe of the liver, with normal FDG uptake.
The main portal vein was not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder is normal in shape and size, with no thickening of the gallbladder wall and no abnormal FDG uptake in the affected area.
The pancreas is 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 has slightly uneven density, but no abnormal FDG uptake.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows in the parenchyma, no widening of the renal pelvis, calyces, or ureters, and no obvious abnormal FDG uptake.
Bilateral adrenal glands show no obvious abnormalities on contrast.
The stomach is poorly filled, with slight thickening of the gastric fundus wall in some areas, and increased FDG metabolism (SUVmax = 3.2).
The intestines are poorly filled, with increased FDG metabolism in some areas (SUVmax = 3.5).
The prostate is normal in size and density, with no abnormally increased FDG uptake.
The bladder is generally full, with no obvious positive stones.
No enlarged lymph nodes are seen in the abdominal cavity, pelvis, or retroperitoneal region, and FDG metabolism is normal.
No obvious fluid accumulation is seen in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral body margin osteophytes, L4/5 and L5/S1 intervertebral disc bulging, and no abnormalities in FDG uptake.
No abnormal FDG metabolism was observed in the entire skeleton.

Impression

1. a. A mass in the lateral basal segment of the right lower lobe with mildly increased FDG uptake, suggestive of cystic lung cancer. b. Several miliary chronic inflammatory nodules in the remaining right lung. Slight thickening of the pleura bilaterally.

2. Slight thickening of the gastric fundus wall with mildly increased FDG uptake, suggestive of chronic gastritis; increased FDG uptake in some intestinal segments, suggestive of inflammatory or physiological uptake. Follow-up gastroscopy and colonoscopy are recommended.

3. Liver cyst. Spleen density is uneven, FDG uptake is normal; follow-up ultrasound is recommended.

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

5. Cranial scintigraphy is normal. Bilateral chronic ethmoid sinusitis. Bilateral chronic inflammation of the palatine tonsils and oropharynx.

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.
