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 in FDG uptake were observed.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical and showed no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed; the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; no abnormalities in FDG uptake were observed; 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 in FDG uptake were observed.
The palatine tonsils showed physiological uptake bilaterally.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
Focal FDG uptake was observed in the right lobe of the thyroid gland (SUVmax = 2.4).
The left lobe of the thyroid gland was normal in morphology and size, with uniform density; no abnormalities in FDG uptake were observed.
Several small lymph nodes, approximately 0.7 cm in short diameter, were observed in the bilateral deep cervical spaces and submandibular region; FDG metabolism was normal.
A nodule approximately 1.7 cm in diameter was observed in the posterior segment of the left upper lobe, with indistinct borders, fine spiculations around the periphery, and traction depression in the adjacent oblique fissure; FDG metabolism was elevated, with SUVmax = 8.8.
A 1.6 1.0 cm cystic nodule with thickened walls and ground-glass opacity was observed in the right middle lobe; FDG metabolism was normal.
Multiple small nodules with relatively clear borders, the largest approximately 0.4 cm in diameter, were observed in the remaining right lung and left lower lobe; FDG metabolism was normal.
A few linear opacities were observed in the medial segment of the right middle lobe and the inferior lingular segment of the left upper lobe; FDG metabolism was normal.
There was no pleural effusion or pneumothorax bilaterally.
Multiple enlarged lymph nodes were observed in the right hilum, pretracheal space of the mediastinum, and aortic window; the largest, approximately 1.1 cm in short diameter, was located in the aortic window; FDG metabolism was elevated, with SUVmax = 5.5.
The cardiac imaging was normal.
The esophagus showed no dilation, thickening or masses in the esophageal wall, and no increased FDG uptake.
Both breasts were relatively dense, and FDG metabolism was normal.
The liver showed no significant abnormalities in shape or size, with smooth borders, no widening of the hepatic fissure, and a small cystic lesion in the right anterior lobe of the liver; FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape or size, no thickening of the gallbladder wall, increased density of contents, and no abnormal local FDG uptake.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no significant 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 significant abnormal density shadows in the parenchyma, no widening of the renal pelvis, calyces, or ureters, and no significant abnormal FDG uptake.
Bilateral adrenal gland imaging showed no significant abnormalities.
The stomach is poorly filled, but the stomach wall is not significantly thickened, and FDG uptake is normal.
The intestines are poorly filled, but the intestinal wall is not significantly thickened or lumpy, and FDG uptake is normal.
There are no post-uterine changes.
No abnormal FDG metabolism is observed in the bilateral adnexa.
The bladder is generally full, and no obvious positive stones are seen.
No enlarged lymph nodes are seen in the abdominal cavity, pelvis, or retroperitoneum, and FDG metabolism is normal.
No significant fluid accumulation is seen in the abdomen or pelvis.
The spinal alignment is normal, with some vertebral marginal osteophytes and L4/5 intervertebral disc bulging, but FDG uptake is normal.
Systemic bone marrow FDG metabolism is normal.

Impression

  1. a. A mass in the posterior segment of the left upper lobe, with increased FDG metabolism, suggestive of peripheral lung cancer. b. Reactive hyperplasia of right hilar and mediastinal lymph nodes, with metastasis to the larger lymph nodes at the aortic window to be ruled out. c. A cystic nodule in the right middle lobe, with thick walls and ground-glass opacity, normal FDG metabolism, suggestive of cystic lung cancer. Multiple inflammatory lymph nodes in the remaining right lung and left lower lobe, follow-up recommended to rule out metastasis. d. A few fibrotic foci in the medial segment of the right middle lobe and the inferior lingular segment of the left upper lobe.

  2. Focal increased FDG metabolism in the right lobe of the thyroid gland, suggestive of inflammatory uptake, ultrasound examination recommended.

  3. Small cyst in the right anterior lobe of the liver. Gallbladder bile concentration. Post-uterine surgery changes.

  4. Spinal osteophyte formation, L4/5 intervertebral disc bulge.

  5. Normal FDG metabolism in the brain. Reactive hyperplasia of bilateral deep cervical and submandibular lymph nodes.

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.
