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; a linear low-density lesion was seen in the right basal ganglia region; FDG uptake was not significantly abnormal.
The ventricles, sulci, fissures, and cisterns were widened; FDG uptake was not significantly abnormal.
The ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical, and no significant abnormalities were observed.
The right maxillary sinus mucosa was thickened, filling the sinus cavity; the sinus walls were intact.
The nasopharyngeal wall was not thickened; FDG uptake was not abnormal.
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; FDG uptake was not abnormal.
The 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.
Increased translucency in both lungs, with multiple air-filled cavities; an irregular mass measuring approximately 3.0 2.8 cm was seen in the posterior segment of the left lower lobe, with lobulated and spiculated margins; FDG metabolism was increased, SUVmax = 11.8; an irregular mixed ground-glass nodule measuring approximately 1.9 1.2 cm was seen in the anterior segment of the right upper lobe, with irregular borders; FDG metabolism was slightly increased, SUVmax = 2.1.
Several small solid nodules were found in both lungs, with a long diameter of approximately 0.2?.4 cm and clear borders; FDG metabolism was normal.
A few patchy opacities and linear lesions were also seen in both lungs; FDG metabolism was normal.
No pleural thickening was seen bilaterally; there was no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
The cardiac silhouette appeared normal.
Some arterial walls showed calcification (including the coronary arteries).
The esophagus showed no dilation, no significant thickening or mass in the wall, and no increased FDG uptake.
The liver's shape and size were normal, 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 of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder's shape and size were normal, the gallbladder wall was not thickened, and local FDG uptake was normal.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma; the main pancreatic duct was not widened, and FDG uptake was normal.
The spleen's shape, size, density, and FDG uptake were normal.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows seen in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is normal.
Bilateral adrenal gland imaging shows no obvious abnormalities.
The stomach is poorly filled, with no obvious thickening of the stomach wall, and FDG uptake is normal.
The intestines are poorly filled, with no obvious thickening or mass in the intestinal wall; FDG uptake is physiological.
The prostate is normal in shape and size, with uniform density, and no abnormal FDG metabolism is seen.
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 effusion is seen in the abdominal or pelvic cavities.
Kyphosis of the spine is present, with osteophyte formation at the margins of some vertebral bodies, and L4/5 and L5/S1 intervertebral disc bulges.
No abnormalities were observed in systemic bone marrow FDG metabolism.

Impression

1. a. Mass in the posterior segment of the left lower lobe, with increased FDG metabolism, suggestive of lung cancer. b. Mixed ground-glass nodules in the anterior segment of the right upper lobe, with mild FDG uptake, highly suggestive of lung cancer; inflammation to be ruled out. Short-term HRCT follow-up is recommended for comparison. c. Several small, solid, chronic inflammatory nodules in both lungs. Scattered chronic inflammation and old lesions in both lungs. Emphysema in both lungs. d. Calcification of some arterial walls (including coronary arteries).

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

3. Bilateral deep cerebral ischemia, softening lesions in the right basal ganglia, age-related brain. Chronic inflammation of the right maxillary sinus.

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.
