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.
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 significant abnormalities.
No thickening was observed in the paranasal sinus mucosa, and the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; no abnormalities were observed in FDG uptake; the pharyngeal recesses were symmetrical; 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.
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.
An irregular mass measuring approximately 8.5 5.7 7.4 cm was observed in the right upper lobe near the hilum, with lobulated margins and elevated FDG metabolism (SUVmax = 12.9).
Multiple punctate and patchy shadows were observed around the mass, indicating stenosis or occlusion of the right upper lobe bronchus.
A small solid nodule, approximately 0.2 cm in long diameter, was observed in the posterior segment of the right lower lobe, with normal FDG metabolism.
A few linear shadows were observed in both lower lobes, with normal FDG uptake.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax.
Multiple enlarged lymph nodes were observed in the right hilum, right upper trachea-mediastinum, pretracheal space, and below the carina, with some lesions having indistinct boundaries from the right upper lobe mass.
These lesions showed elevated FDG metabolism (SUVmax = 11.4).
The cardiac silhouette was normal.
The esophagus was not dilated, and the esophageal wall showed no significant thickening or mass; FDG uptake was not increased.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissures.
Plain CT scan showed no obvious abnormal density shadows in the liver parenchyma, and FDG uptake was normal.
The main portal vein showed no obvious widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape and size, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas was 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 showed no abnormalities in shape, size, density, or FDG uptake.
Small cystic lesions were observed in both kidneys, approximately 0.3 cm in long diameter; FDG metabolism was normal; the renal pelvis, calyces, and ureters were not widened, and FDG uptake was normal.
Bilateral adrenal gland imaging showed no obvious abnormalities.
The stomach was poorly distended, with no obvious thickening of the stomach wall and no obvious abnormal FDG uptake.
The intestines were poorly distended, with no obvious thickening or mass in the intestinal wall; FDG uptake was physiological.
The prostate is of normal size, with punctate calcifications visible within; FDG uptake is not abnormally elevated.
The bladder is generally full, with no obvious positive stones.
No enlarged lymph nodes are seen in the abdominal cavity, pelvis, or retroperitoneal region; FDG metabolism is normal.
No significant fluid accumulation is seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with minor osteophyte formation at the margins of some vertebral bodies; L4/5 and L5/S1 intervertebral disc bulges are present; FDG uptake is normal.
No abnormal FDG metabolism is observed in the entire skeletal system.

Impression

1. A mass near the hilum in the right upper lobe, with elevated FDG metabolism, suggestive of central lung cancer with obstructive inflammation. Multiple lymph node metastases in the right hilum and mediastinum.

2. Chronic inflammatory miliary nodules in the posterior segment of the right lower lobe. A few old lesions in both lower lobes.

3. Minimal renal cysts in both kidneys. Calcifications in the prostate.

4. Mild osteophyte formation in the cervical, thoracic, and lumbar spine. L4/5 and L5/S1 disc bulges.

5. No abnormalities 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.
