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: Brain morphology and structure were normal, with punctate, slightly low-density shadows in the deep brain regions; FDG metabolism was normal.
The ventricles, sulci, fissures, and cisterns were widened, but local density and FDG uptake were normal; there was no midline shift.
Both eyes were symmetrical, with no obvious abnormalities.
The bilateral ethmoid sinuses and left maxillary sinus mucosa were slightly thickened; the remaining paranasal sinuses showed no thickening, and the sinus walls were intact.
The nasopharyngeal wall was not thickened, and FDG uptake was normal.
The bilateral pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal fossa and pterygopalatine fossa structures were normal, and the bilateral parapharyngeal spaces were clear with no abnormal FDG uptake.
A punctate, dense shadow was seen in the right palatine tonsil; both palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx are normal.
The thyroid gland is normal in shape and size, but its density is somewhat uneven.
Two low-density nodules with calcification are seen in the right lobe, with a long diameter of approximately 1.9 cm.
FDG uptake is normal.
No enlarged lymph nodes are seen in the bilateral deep cervical spaces or submandibular region.
Both lungs show clear lung markings.
An irregular soft tissue mass is observed in the posterior segment of the left upper lobe, with clear borders, uneven density, and low-density necrotic areas.
It measures approximately 8.0*6.0*8.8cm and shows unevenly increased FDG uptake (SUVmax=21.6).
The mass is poorly demarcated from the adjacent pleura, and the adjacent bronchus is truncated.
Another irregular soft tissue mass is observed in the anterior segment of the left upper lobe, with lobulated and spiculated edges, partially tractioning the adjacent pleura.
It has uneven density and measures approximately 3.1*2.1cm.
FDG uptake is increased (SUVmax=11.4), and the adjacent anterior segment bronchus of the left upper lobe is truncated.
Both lungs show diffusely distributed solid nodules of varying sizes with clear borders, the largest being approximately 0.5cm in diameter.
No abnormal FDG uptake was observed in these nodules.
Scattered linear lesions are also observed in both lungs, with no abnormal FDG uptake.
Multiple enlarged lymph nodes were observed in the left hilum, pretracheal space, para-aortic arch, aortopulmonary window, subcarinal region, and left supraclavicular fossa.
The largest lymph node had a short diameter of approximately 2.3 cm.
FDG uptake was increased, with an SUVmax of 21.1.
The cardiac silhouette appeared normal, with cardiac chamber density lower than myocardial density.
Calcification was observed in some arterial walls (including the coronary arteries).
The esophagus showed no dilation, but continuous FDG uptake was observed in the middle and lower segments, with an SUVmax of 5.9.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissures.
Several calcified foci and multiple cystic foci were observed in the liver, the largest being approximately 1.6 cm in diameter.
FDG uptake was normal.
The main portal vein showed no significant dilation, and no dilation was observed in intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape or size, with no thickening of the gallbladder wall and no abnormalities in localized FDG uptake.
The pancreas is normal in shape, with no obvious abnormal density shadows seen 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 several dense nodules in the renal calyces, approximately 0.3 cm in diameter.
A cystic low-density lesion approximately 1.3 cm in diameter with clear borders is seen in the left renal parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal glands show no significant abnormalities on contrast imaging.
The stomach is partially absent, with slight thickening of the anastomotic wall accompanied by increased FDG uptake (SUVmax = 5.2).
The intestinal tract is not satisfactorily filled, with considerable gas and residual contents in the lumen.
Localized FDG uptake in the rectum is increased (SUVmax = 16.9).
The prostate is full with calcifications, but FDG uptake is not abnormally increased.
The bladder is poorly filled, but no obvious positive stones are seen.
Systemic bone density is decreased, spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies, and L4/5 and L5/S1 intervertebral disc bulges.
Thickened soft tissue in the chin with increased FDG uptake, SUVmax = 15.8.
Systemic bone marrow FDG metabolism is normal.

Impression

1. a. A mass in the left upper lobe of the lung with increased FDG metabolism, consistent with lung cancer. Multiple lymph node metastases in the left hilum, mediastinum, and left supraclavicular fossa. b. Bilateral lung metastases. Scattered post-inflammatory lesions in both lungs. c. Anemia, partial arterial wall calcification (including coronary arteries).

2. Liver calcifications, multiple liver cysts. Bilateral kidney stones, left renal cyst. Benign prostatic hyperplasia with calcification.

3. Postoperative changes in the stomach; chronic inflammatory changes in the middle and lower esophagus; possible rectal polyps, malignancy to be ruled out. Follow-up gastroscopy and colonoscopy are recommended.

4. a. Osteoporosis, degenerative changes in the spine, L4/5 and L5/S1 intervertebral disc bulges. b. Thickening of the soft tissue in the chin with increased FDG metabolism suggests possible inflammation or physiological uptake; clinical correlation is recommended.

5. Low-density nodule with calcification in the right lobe of the thyroid gland; FDG metabolism is normal, suggesting possible nodular goiter; malignancy is a possibility. Further ultrasound examination is recommended.

6. Elderly brain with deep lacunar infarcts. Chronic inflammation of both ethmoid sinuses and the left maxillary sinus. Calcification of the right palatine tonsil.

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.
