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: Brain morphology and structure were normal, with punctate low-density shadows in the deep cerebral regions bilaterally; FDG uptake was not significantly abnormal.
The ventricular system was enlarged, with widening of the sulci, fissures, and cisterns; the ventricles were symmetrical bilaterally, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no significant abnormalities.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasopharyngeal wall showed no thickening; FDG uptake was normal; the pharyngeal recesses were symmetrical bilaterally; the Eustachian tube openings were not narrowed; the infratemporal and pterygopalatine fossae were structurally normal; the parapharyngeal spaces were clear bilaterally, and FDG uptake was normal.
The palatine tonsils showed physiological uptake bilaterally.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The laryngopharynx showed no abnormalities in morphology and structure.
The thyroid gland is normal in shape and size, with uniform density, and no abnormal FDG uptake was observed.
Post-treatment of right lung cancer: High-density suture shadows are visible in the surgical area, with a few linear shadows around them; no abnormal FDG uptake was observed.
Partial absence of the right 3rd rib; distorted bone structure of the right 4th rib with localized misaligned bony healing; no abnormal FDG uptake was observed.
Multiple solid nodules are seen in both lungs, with smooth margins; the largest is located in the lingular segment of the left upper lobe, with a diameter of approximately 0.6 cm; no abnormal FDG metabolism was observed.
A few linear shadows are seen in both lungs.
Mild thickening of the right pleura; no pleural effusion or pneumothorax on either side.
A small lymph node is visible in the left supraclavicular fossa, with a short diameter of approximately 0.4 cm; mild FDG uptake; SUVmax = 2.1.
No significantly enlarged lymph nodes are seen in the bilateral hilar and mediastinal regions.
Partial calcification of the aorta and coronary artery walls.
The esophagus showed no dilation, no significant thickening or mass in the esophageal wall, and no increased FDG uptake.
The breasts were sparsely populated bilaterally, with no abnormal density shadows, and no abnormal FDG metabolism.
The liver showed no significant abnormalities in shape or size, with smooth liver margins, no widening of the hepatic fissure, uniformly decreased liver parenchyma density, and indistinct intrahepatic vessels; FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder was absent post-operatively, and local FDG uptake was normal.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma; the main pancreatic duct was not widened, and FDG uptake was normal.
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.
Punctate dense shadows were seen in the right renal calyx.
No widening of the bilateral renal pelvis, calyces, or ureters was observed, and FDG uptake showed no significant abnormalities.
Bilateral adrenal gland imaging showed no significant abnormalities.
The stomach was poorly distended, but the gastric wall showed no significant thickening, and FDG uptake showed no significant abnormalities.
The intestines were poorly distended, but the intestinal wall showed no significant thickening or mass, and FDG uptake was physiological.
Nodular bulges were observed at the edge of the uterus, but FDG uptake was not abnormally increased.
No abnormal FDG metabolism was observed in the bilateral adnexa.
The bladder was generally full, and no obvious positive stones were observed.
No enlarged lymph nodes were seen in the abdomen, pelvis, or retroperitoneum, and FDG metabolism was normal.
No significant fluid accumulation was observed in the abdomen or pelvic cavity.
Slight scoliosis in the lumbar spine, osteophyte formation at the margins of some vertebral bodies, calcification of the nuchal ligament, slight posterior displacement of L2 and L3 vertebral bodies, slight anterior displacement of L4 and L5 vertebral bodies, bulging of L3/4, L4/5, and L5/S1 intervertebral discs with pneumothorax, normal FDG uptake.
Punctate dense shadows are seen in the bilateral femoral heads.
Increased FDG metabolism in the bilateral shoulder joint capsules, SUVmax = 2.8.

Impression

1. a. No obvious signs of tumor recurrence in the right lung surgical area. b. Post-operatively, no abnormal density shadows or abnormal FDG metabolic foci were observed in the surgical area following a right 3rd rib lesion. Changes were observed after a fracture of the right 4th rib. c. Multiple nodules in both lungs, more numerous and larger than before, with no abnormal FDG uptake, suggesting a high probability of metastatic tumors. Regular follow-up based on clinical findings and CT scans is recommended. d. Left supraclavicular fossa lymph nodes showed mild FDG uptake and slight enlargement, suggesting a possible metastatic tumor. Regular follow-up based on clinical findings is recommended.

2. Fibrotic lesions in both lungs, mild thickening of the right pleura. Partial calcification of the aorta and coronary artery walls.

3. Fatty liver. Post-operative absence of the gallbladder. Small renal calculus in the right kidney.

4. Uterine fibroids. Scoliosis with degenerative changes. Multiple lumbar vertebral instability. L3/4, L4/5, and L5/S1 intervertebral disc bulging with pneumoconiosis and degeneration. Bilateral femoral head insular cranial fossa. Bilateral frozen shoulder.

5. Bilateral deep lacunar infarcts in the brain, age-related brain changes.

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.
