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: The brain morphology and structure were normal; no abnormal density shadows were seen in the brain parenchyma, and FDG uptake was not significantly abnormal.
The ventricles, sulci, fissures, and cisterns were not widened; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical and without significant abnormalities.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasopharyngeal wall showed no thickening, and FDG uptake was not abnormal.
The pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the parapharyngeal spaces were clear with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
The thyroid gland is normal in shape and size, with uneven density.
Punctate calcifications are seen in the right lobe.
FDG uptake is normal.
No enlarged lymph nodes are seen in the bilateral deep cervical spaces or submandibular region.
An irregular soft tissue mass is seen in the posterior segment of the right lower lobe near the hilum, with a CT value of approximately 38 HU and a size of approximately 3.4 3.0 cm.
FDG metabolism is increased, SUVmax = 9.2, indicating bronchial stenosis in the posterior segment of the right lower lobe.
Multiple soft tissue masses are present in the right pleura (interlobar pleura, mediastinal pleura, costal pleura, and diaphragmatic pleura), the largest being approximately 2.2 cm in long diameter.
FDG metabolism is increased, SUVmax = 8.9.
A few linear and punctate lesions are seen in the remaining lungs, with no abnormal FDG uptake observed.
A small amount of pleural effusion is present in the right side.
Multiple enlarged lymph nodes were observed in the right hilum, pretracheal space of the mediastinum, subcarinal space, and right cardiophrenic angle.
The largest lymph node had a short diameter of approximately 3.1 cm.
FDG metabolism was increased, with SUVmax = 5.9.
The cardiac silhouette appeared normal.
Calcification was observed in some arterial walls (including the coronary arteries).
The esophagus showed no dilation, no significant thickening or mass in the wall, and no increased FDG uptake.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
Plain CT scan showed no significant abnormal density shadows in the liver parenchyma, and no abnormal FDG uptake.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape or size, no thickening of the gallbladder wall, and no abnormal local FDG uptake.
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 not significantly abnormal.
The spleen is normal in shape, size, density, and FDG uptake.
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 not significantly abnormal.
Bilateral adrenal glands show no obvious abnormalities on contrast.
The stomach is poorly distended, with no obvious thickening of the stomach wall, and FDG uptake is not significantly abnormal.
The intestines are poorly distended, with no obvious thickening or mass in the intestinal wall, and FDG uptake is physiological.
The prostate is full in shape, with a transverse diameter of approximately 5.1 cm, and punctate calcifications are seen inside.
No abnormal FDG metabolism is observed.
The bladder is generally full, with no obvious positive stones seen inside.
No enlarged lymph nodes were observed in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The L5 vertebral body showed anterior slippage, bilateral isthmic discontinuity, sacral lumbarization, and osteophyte formation at the margins of some vertebral bodies.
L3/4, L4/5, and L5/S1 intervertebral disc bulges were also observed.
A bony density shadow was seen in the left iliac bone.
Decreased bone density was observed in the right iliac bone and right scapula, with increased FDG metabolism and an SUVmax of 3.6.

Impression

1. a. A mass near the hilum in the posterior segment of the right lower lobe, with increased FDG metabolism, suggestive of central lung cancer; extensive metastasis to the right pleura (interlobar pleura, mediastinal pleura, costal pleura, diaphragmatic pleura). Multiple lymph node metastases in the right hilum, mediastinum, and right cardiophrenic angle. b. Minor chronic inflammation in the remaining lungs. Small amount of pleural effusion on the right side. Calcification of some arterial walls (including coronary arteries). c. Decreased bone density in the right iliac bone and right scapula, with increased FDG metabolism; bone metastasis to be ruled out, MRI follow-up recommended.

2. Uneven thyroid density, calcification in the right lobe; please combine with ultrasound examination.

3. Benign prostatic hyperplasia with calcification.

4. Degenerative changes in the spine; L3/4, L4/5, L5/S1 intervertebral disc bulge. L5 vertebral body anteriorly slipped, bilateral vertebral arch disintegration. Left iliac bone island.

5. Cranial scintigraphy showed no abnormalities.

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.
