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: 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 bilaterally; and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no significant abnormalities.
No thickening was observed in the paranasal sinus mucosa; 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 bilaterally; there was no narrowing of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the bilateral parapharyngeal spaces were clear; and no abnormalities were observed in FDG uptake.
The palatine tonsils showed physiological uptake bilaterally.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
The thyroid gland was normal in shape and size, with slightly uneven density; no abnormalities were observed in FDG uptake.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
A solid nodule measuring approximately 1.2 x 1.1 cm was observed in the anterior basal segment of the right lower lobe, containing a cavity with spiculated and lobulated margins, traction on the pleura.
Mild FDG metabolism was observed, with an SUVmax of 1.0.
Scattered small solid nodules with clear borders, approximately 0.2-0.3 cm in long diameter, were observed in the upper lobes of both lungs and the right lower lobe.
FDG uptake was normal.
A bronchus in the left lower lobe was obstructed, and the lower lobe was atelectasis.
FDG metabolism was increased, with an SUVmax of 3.5.
Scattered linear opacities were observed in both lungs.
No pleural thickening or pleural effusion/pneumothorax was observed bilaterally.
No significantly enlarged lymph nodes were observed in the hilum or mediastinum bilaterally.
The cardiac silhouette was normal.
No esophageal dilatation, significant wall thickening, or mass was observed, and FDG uptake was normal.
No significant abnormalities were observed in either breast, and FDG metabolism was normal.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissure.
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 the intrahepatic and extrahepatic bile ducts were not dilated.
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.
Both kidneys were 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 showed no obvious abnormalities on contrast.
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 a local soft tissue shadow in the rectum measuring approximately 1.6*0.5cm, showing increased FDG metabolism (SUVmax = 12.0).
The uterus is normal in shape, with no abnormal density shadows, and FDG uptake is not abnormally increased.
No abnormal FDG metabolism is observed in the bilateral adnexa.
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 fluid accumulation is seen in the abdominal or pelvic cavities.
A linear density increase and calcification are observed in the subcutaneous tissue of the right buttock.
The spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies and localized dense shadows in some lumbar vertebrae.
Systemic bone marrow FDG metabolism is normal.

Impression

1. a. Solid nodule in the anterior basal segment of the right lower lobe with slightly elevated FDG metabolism, suggestive of lung cancer; atypical granulomatous lesion to be ruled out. Pathological examination is required for confirmation. b. Several chronic inflammatory miliary nodules in the upper lobes of both lungs and the right lower lobe. Atelectasis in the left lower lobe, no definite space-occupying lesion seen. A few fibrotic lesions in both lungs.

2. Localized soft tissue lesions in the rectum with elevated FDG metabolism, suggestive of polyps; local malignancy to be ruled out. Colonoscopy is recommended for further examination.

3. Partial vertebral osteophyte formation. Partial lumbar vertebral island formation. Subcutaneous calcification and inflammatory remnants in the right buttock.

4. No obvious abnormalities were seen 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.
