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 tomography showed:Normal brain morphology and structure, with punctate low-density lesions in the deep bilateral cerebral regions; no significant abnormalities in FDG metabolism.
Enlargement of the ventricles, sulci, fissures, and cisterns; symmetrical bilateral ventricles; no midline shift.
Normal bilateral eyeball morphology and contour; clear retrobulbar structures; symmetrical bilateral optic nerves; no abnormal FDG metabolism.
No thickening of the paranasal sinus mucosa; intact sinus walls.
No thickening of the nasopharyngeal wall; no stenosis of the bilateral pharyngeal recesses and Eustachian tube openings; normal structures of the infratemporal fossa and pterygopalatine fossa; clear bilateral parapharyngeal spaces; no abnormal FDG metabolism.
Physiological FDG metabolism in the oropharynx and laryngopharynx.
No abnormal contrast enhancement of the bilateral parotid and submandibular glands.
Poor pneumatization of the bilateral mastoid processes.
The thyroid gland is normal in shape and size, with uniform density, and FDG metabolism is normal.
No significantly enlarged lymph nodes are seen in the bilateral deep cervical spaces, submandibular region, or submental region.
Increased and disordered lung markings are observed bilaterally, with increased lung translucency and a few reticular shadows.
Cystic lucent shadows are seen in the subpleural region of both lungs, the largest measuring approximately 7.5 cm in length.
A paravertebral mass is present in the right lower lobe, infiltrating and adhering to the pleura, with a cross-sectional size of approximately 7.1*4.2*5.0 cm, showing increased FDG metabolism (SUVmax = 7.4).
Scattered solid micronodules are present in both lungs, with regular shape and clear borders, measuring approximately 0.3-0.5 cm in length, and FDG uptake is normal.
A few linear and flocculent density shadows are also seen in both lungs, with FDG metabolism normal.
The pleura is slightly thickened bilaterally, but there is no pleural effusion or pneumothorax.
Right hilar and mediastinal (pretracheal, posterior to the vena cava, subcarinal) lymph nodes are visible; the largest has a short diameter of approximately 1.1 cm, with slightly increased FDG metabolism and an SUVmax of 2.7.
The cardiac silhouette is normal.
Some arterial walls show calcification (including the coronary arteries).
The liver's shape and size are normal; the liver margins are smooth, the hepatic fissure is not widened, and no obvious abnormal density shadows are seen in the liver parenchyma on plain CT scan; FDG metabolism is normal.
The main portal vein is not significantly widened, and no dilation is seen in the intrahepatic or extrahepatic bile ducts.
The gallbladder is smaller, with slightly thickened and roughened walls; local FDG metabolism is normal.
The pancreas is normal in shape; no obvious abnormal density shadows are seen in the parenchyma; the main pancreatic duct is not widened; FDG metabolism is normal.
The spleen's shape, size, density, and FDG metabolism are normal.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows seen in the parenchyma.
Punctate dense shadows are seen in the right renal calyx.
No widening of the renal pelvis, calyces, or ureters is observed, and FDG metabolism is normal.
No obvious abnormalities are seen on bilateral adrenal gland contrast.
The esophagus is not dilated, and the wall is not significantly thickened or swollen.
FDG metabolism is not increased.
Gastric distension is poor, with slight thickening of the antral wall and a slightly increased FDG metabolism (SUVmax = 1.7).
Intestinal distension is poor, with no significant thickening or swollen intestinal wall, and FDG metabolism is physiological.
The prostate is enlarged, with a transverse diameter of approximately 5.2 cm.
High-density shadows are seen in the parenchyma, and FDG metabolism is normal.
Bladder distension is poor, and no obvious positive stones are seen.
Calcifications are present in the right scrotum, but FDG metabolism is absent.
Retroperitoneal lymph nodes at the level of the superior mesenteric artery are visible; the largest has a short diameter of approximately 0.6 cm, with slightly increased FDG metabolism and an SUVmax of 1.7.
No significant fluid accumulation is observed in the abdominal or pelvic cavities.
The spinal alignment is normal, with some vertebral body margin osteophytes.
L4/5 and L5/S1 intervertebral disc bulges, with normal FDG metabolism.
L5/S1 intervertebral disc shows pneumatosis and degeneration.
The right second lateral rib and S2 show uneven bone density, with increased FDG metabolism and an SUVmax of 3.6.

Impression

1. a. A space-occupying lesion in the right lower lobe, paravertebral, with pleural infiltration and adhesion, and increased FDG metabolism, consistent with lung cancer; the tumor is still active. Metastasis to the right hilar and some mediastinal lymph nodes is highly probable. b. Uneven bone density in the right second rib and S2 region, with increased FDG metabolism, suggesting a high probability of bone metastasis; please compare with previous images. c. Chronic bronchitis and emphysema-like changes in both lungs, with bullae. A small amount of chronic inflammation in both lungs. Scattered chronic inflammatory micronodules (solid) in both lungs; please follow up with CT scans. Mild pleural thickening bilaterally. Partial arteriosclerosis (including coronary arteries).

2. Chronic cholecystitis. Small kidney stone in the right kidney. Benign prostatic hyperplasia with calcification. Calcification lesion in the right testicular tunica vaginalis. Possible reactive hyperplasia of retroperitoneal lymph nodes; follow-up with CT or ultrasound is recommended.

3. Chronic antral gastritis.

4. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulge. L5/S1 intervertebral disc pneumothorax and degeneration.

5. Age-related brain changes, deep lacunar infarcts in the brain; MRI is recommended. Bilateral mastoid hypopneumatization.

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.
