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, and resting, a whole-body PET/CT scan was performed.
The whole-body scan showed: The brain morphology and structure were normal, with no abnormal density shadows in the brain parenchyma, and no significant abnormalities in FDG uptake.
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, with no significant 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, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear with no abnormal FDG uptake.
Increased FDG metabolism was observed in both palatine tonsils, with SUVmax = 9.1.
No abnormal density shadows were observed 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.
Bronchiectasis was observed in the posterior segment of the left lower lobe, containing an irregularly shaped soft tissue density shadow measuring approximately 4.5*1.9cm; FDG metabolism was increased, SUVmax=7.2.
Several solid micronodules with clear borders and a long diameter of approximately 0.2-0.3cm were seen in the lower lobes of both lungs and the left interlobar fissure; FDG uptake was normal.
No pleural thickening was observed 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.
No esophageal dilation was observed; the esophageal wall showed no significant thickening or mass; FDG uptake was normal.
The liver's shape and size are normal, with smooth borders and no widening of the hepatic fissure.
No abnormal density shadows were observed in the liver parenchyma on plain CT scan, 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 are normal, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
A dense shadow with a long diameter of approximately 0.5 cm is seen in the gallbladder neck.
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 normal.
The spleen's shape, size, density, and FDG uptake are normal.
Accessory splenic nodules are visible.
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 normal.
Bilateral adrenal gland imaging is normal.
Stomach distension is poor, with no obvious thickening of the stomach wall, and no obvious abnormalities in FDG uptake.
Intestinal distension is poor, with no obvious thickening or mass in the intestinal wall, and FDG uptake is physiological.
Prostate size and shape are normal, with calcifications seen, and no abnormal FDG metabolism observed.
Bladder distension is normal, with no obvious positive stones seen.
No enlarged lymph nodes were seen in the abdominal cavity, pelvis, or retroperitoneal region.
No obvious fluid accumulation was seen in the abdominal or pelvic cavities.
Spinal alignment is normal, with high-density shadows seen below the endplates at the relative margins of the T10-T11 vertebral bodies, and gas shadows seen in the T10/11 intervertebral disc, with no abnormalities in FDG uptake.
Systemic bone marrow FDG metabolism is normal.

Impression

1. a. A space-occupying lesion in the posterior segment of the left lower lobe bronchus with increased FDG metabolism, consistent with carcinoid features based on pathology. b. Several solid micronodules in the lower lobes of both lungs and the left interlobar fissure, with normal FDG uptake, suggestive of chronic inflammatory nodules, metastasis to be ruled out; please review with CT for comparison.

2. T10-T11 vertebral endplate inflammation. T10/11 intervertebral disc pneumothorax.

3. Gallstones. Accessory spleen.

4. Prostatic calcification.

5. Chronic inflammation of both palatine tonsils. No obvious abnormalities were found on cranial scintigraphy.

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.
