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 were seen in the deep bilateral cerebral regions; no abnormal density shadows were seen in the remaining brain parenchyma.
FDG uptake was normal.
No widening was observed in the ventricles, sulci, fissures, or cisterns.
The ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical and showed no obvious abnormalities.
The mucosa of the bilateral maxillary and ethmoid sinuses was thickened, but the sinus walls were intact.
The nasopharyngeal wall was not thickened, and FDG uptake was normal.
The bilateral 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 normal FDG uptake.
The bilateral palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx were normal.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
An irregular mass, approximately 6.8 5.7 cm in size, with lobulated spiculated margins, is seen in the left lower lobe adjacent to the oblique fissure; FDG metabolism is increased, SUVmax = 15.5.
A small ground-glass nodule, approximately -612 HU on CT, with a long diameter of approximately 0.3 cm and relatively clear borders, is seen in the lateral basal segment of the left lower lobe; FDG metabolism is normal.
A few punctate and linear lesions are also seen in both lungs; FDG metabolism is normal.
No pleural thickening was seen bilaterally; there was no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal.
The esophagus was not dilated; the esophageal wall was not significantly thickened or lumped; FDG uptake was normal.
The stomach is poorly distended, with no significant thickening of the stomach wall, and no obvious abnormalities in FDG uptake.
The intestines are poorly distended, with continuous FDG metabolism increased in parts of the colon and rectum (SUVmax = 5.6).
The liver is normal in shape and size, with smooth borders and no widening of the hepatic fissures; multiple cystic lesions are seen within the liver, the largest being approximately 0.8 cm in length, with absent FDG uptake; punctate calcifications are seen in the right lobe of the liver.
The liver parenchyma has decreased density, with a CT value of approximately 44 HU, and no abnormalities in FDG metabolism.
The main portal vein is not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts is observed.
The gallbladder is normal in shape and size, with no thickening of the gallbladder wall, increased density within the lumen, and no abnormalities in FDG uptake.
The pancreas shows fatty infiltration, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormalities in FDG uptake.
Spleen morphology, size, density, and FDG uptake were normal.
A cystic lesion measuring approximately 3.7 2.5 cm was observed in the right kidney, with absent FDG uptake.
The left kidney was normal in shape and size, with no obvious abnormal density shadows in the parenchyma, and no widening of the renal pelvis, calyces, or ureter; FDG uptake was normal.
Bilateral adrenal gland imaging showed no obvious abnormalities.
The prostate was normal in shape and size, with punctate calcifications observed; no abnormal FDG metabolism was observed.
The bladder was generally full, with no obvious positive stones.
No enlarged lymph nodes were observed in the abdomen, pelvis, 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 bulging.
Systemic bone marrow FDG metabolism was normal.

Impression

1. a. A mass adjacent to the oblique fissure in the lower lobe of the left lung, with increased FDG metabolism, suggestive of lung cancer; please correlate with clinicopathology. b. A ground-glass nodule in the lateral basal segment of the lower lobe of the left lung, with normal FDG metabolism, suggestive of inflammatory nodule or atypical adenomatous hyperplasia; annual HRCT follow-up is recommended. c. A few chronic inflammations and old lesions in both lungs.

2. Liver cysts; liver calcifications. Mild fatty liver. Pancreatic fatty infiltration. Possible cholestasis; ultrasound examination recommended. Right renal cyst.

3. Continuous increased FDG metabolism in part of the colon and rectum, suggestive of inflammatory or physiological uptake; colonoscopy recommended.

4. Prostatic calcification; follow-up PSA and ultrasound examination recommended.

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

6. A few ischemic lesions in the deep bilateral brain regions; MRI follow-up is recommended. Chronic inflammation of the bilateral maxillary and ethmoid sinuses.

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.
