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, with no abnormal density shadows in the brain parenchyma, and no significant abnormalities in FDG uptake.
The ventricular system was slightly enlarged, with widening of the sulci, fissures, and cisterns.
The ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical, 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, and FDG uptake was normal.
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.
A low-density nodule with relatively clear borders, measuring approximately 0.5 0.6 cm, is seen in the right lobe of the thyroid gland.
FDG metabolism is normal.
The left lobe of the thyroid gland is normal in shape and size, with uniform density; FDG uptake is normal.
Multiple lymph nodes are visible in the bilateral supraclavicular fossa and posterior cervical triangle, the largest measuring approximately 0.9 cm in short diameter.
FDG metabolism is increased, with an SUVmax of 8.6.
An irregular mass measuring approximately 3.0 1.8 cm is visible in the posterior basal segment of the left lower lobe of the lung.
The boundary with the adjacent pleura is indistinct, and FDG uptake is increased, with an SUVmax of 8.1.
Diffuse nodular shadows are seen in both lungs and the interlobar pleura, the largest measuring approximately 1.5 cm in long diameter.
Some nodules show mild FDG uptake, with an SUVmax of 3.4.
A few flocculent density shadows are seen in both lungs; FDG metabolism is normal.
A small amount of fluid density shadows are visible in both pleural cavities.
Multiple lymph nodes were observed in the left hilum and mediastinum, the largest measuring approximately 0.9 cm in short diameter, with increased FDG metabolism and an SUVmax of 5.9.
The cardiac silhouette appeared normal.
The esophagus showed no dilation, wall thickening, or mass, and FDG uptake was not increased.
Both breasts were relatively dense, with no abnormal FDG metabolism.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
Two low-density nodules with indistinct borders were observed in the left medial lobe of the liver, with increased FDG uptake; the larger nodule measured approximately 1.6 1.5 cm, and had an SUVmax of 6.4.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder wall was slightly thickened and rough, with no abnormalities in 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.
Cystic lesions are visible in both kidneys, the largest being approximately 1.0 cm in long diameter; FDG metabolism is not abnormal.
The right kidney is normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureter are not widened; FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging is normal.
The stomach is poorly distended; the stomach wall is not significantly thickened; FDG uptake is not significantly abnormal.
The intestines are poorly distended; the intestinal wall is not significantly thickened or has masses; FDG uptake is physiological.
The uterus is full, with a nodular protrusion at the left posterior margin and calcifications visible at the edge; FDG uptake is not abnormally increased.
No abnormal FDG metabolism was observed in the bilateral adnexa.
The bladder was generally full, with no obvious positive stones.
A tortuous and dilated blood vessel was visible subcutaneously on the left anterior pelvic wall; FDG metabolism was normal.
No enlarged lymph nodes were observed in the abdominal cavity, pelvis, or retroperitoneal region; FDG metabolism was normal.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulging.
Cystic lesions were observed in the sacral canal, with absent FDG uptake.
Abnormal density changes were observed in multiple bone areas throughout the body (bilateral humerus, bilateral proximal femur, bilateral clavicles, bilateral scapulae, sternum, multiple ribs, spine, and pelvis); FDG metabolism was increased, with SUVmax = 10.3.

Impression

1. a. A mass in the posterior basal segment of the left lower lobe, with elevated FDG metabolism, suggestive of lung cancer; multiple lymph node metastases in the left hilum, mediastinum, bilateral supraclavicular fossa, and posterior cervical triangle. b. Multiple metastatic tumors in the pleura of both lungs and bilateral interlobar pleura; liver metastases; multiple bone metastases throughout the body. Small amount of pleural effusion bilaterally.

2. Chronic inflammation or fibrosis in both lungs.

3. Chronic cholecystitis. Small renal cysts in both kidneys. Uterine fibroids. Subcutaneous varicose veins on the left anterior pelvic wall.

4. Low-density nodule in the right lobe of the thyroid gland, with normal FDG metabolism, suggestive of nodular goiter or adenoma; ultrasound re-examination recommended.

5. Spinal osteophyte formation, L4/5 and L5/S1 intervertebral disc bulge. Sacral canal cyst.

6. Senile cerebral atrophy.

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.
