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: A few punctate low-density shadows were seen in the deep bilateral brain regions; FDG uptake was not significantly abnormal.
Mild widening of the ventricles, sulci, fissures, and cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no obvious abnormalities.
A small amount of mucosal thickening was observed in the bilateral maxillary sinuses; the sinus walls were intact.
No thickening was observed in the nasopharyngeal walls; FDG uptake was not abnormal.
The bilateral pharyngeal recesses were symmetrical; there was no stenosis of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the bilateral parapharyngeal spaces were clear, and FDG uptake was not abnormal.
The bilateral palatine tonsils showed physiological uptake.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx were normal.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
An irregular mass measuring approximately 3.5 3.2 3.7 cm was observed in the posterior segment of the left upper lobe, with lobulated and spiculated margins.
FDG metabolism was increased (SUVmax = 9.9), with distal bronchial occlusion and scattered patchy shadows around it.
A strip-like area of increased density was observed in the anterior segment of the left upper lobe, with increased FDG metabolism (SUVmax = 3.4).
Multiple solid micronodules, approximately 0.2?.4 cm in long diameter, with clear borders, were observed in both lungs; FDG metabolism was normal.
Multiple scattered patchy opacities and linear foci were also observed in both lungs; FDG metabolism was normal.
The pleura was slightly thickened bilaterally; there was no pleural effusion or pneumothorax bilaterally.
Multiple enlarged lymph nodes were observed in the left hilum, left superior mediastinum near the trachea, aortic window, left internal mammary chain, and left supraclavicular fossa.
The largest was located in the left hilum, with a short diameter of approximately 2.0 cm.
FDG metabolism was increased, with SUVmax = 14.4.
The cardiac silhouette was normal, with a small amount of effusion in the superior pericardial recess.
Some arterial walls showed calcification.
The esophagus was not dilated, and the wall was not significantly thickened or swollen; FDG uptake was not increased.
Gastric distension was poor, and the gastric wall was not significantly thickened; FDG uptake was not significantly abnormal.
Intestinal distension was poor, and the intestinal wall was not significantly thickened or swollen; FDG uptake was physiological.
The liver's shape and size were normal, with smooth borders and no widening of the hepatic fissure.
Plain CT scan showed no significant abnormal density shadows in the liver parenchyma; FDG uptake was normal.
The main portal vein was not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder is normal in shape and size, the gallbladder wall is not thickened, and local FDG uptake is normal.
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 normal.
The spleen is normal in shape, size, density, and FDG uptake.
The left kidney shows punctate dense shadows, and a patchy low-density lesion is seen at the upper pole of the left kidney.
The right kidney is normal in shape and size, with no obvious abnormal density shadows in the parenchyma, and the renal pelvis, calyces, and ureter are not widened; FDG uptake is normal.
Bilateral adrenal gland contrast is normal.
The prostate is full, with uniform density, and no abnormal FDG metabolism is observed.
The bladder is generally full, and no obvious positive stones are seen within it.
No enlarged lymph nodes are seen in the abdomen, pelvis, or retroperitoneal region.
No obvious fluid accumulation was observed in the abdomen or pelvis.
The spinal alignment was normal, with some vertebral body margins showing osteophyte formation, and L4/5 and L5/S1 intervertebral disc bulging.
Bone destruction was observed in both scapulae, right clavicle, sternum, multiple ribs bilaterally, multiple vertebral bodies and appendages of the spine, sacrum, multiple areas of the pelvis, and the upper segment of the right femur.
FDG metabolism was elevated, with SUVmax = 14.3.

Impression

1. a. A mass in the posterior segment of the left upper lobe, with elevated FDG metabolism, suggestive of lung cancer with surrounding obstructive inflammation; multiple lymph node metastases in the left hilum, mediastinum, left internal mammary chain, and left supraclavicular fossa; widespread bone metastases throughout the body. b. A patchy shadow in the anterior segment of the left upper lobe, with elevated FDG metabolism, highly suggestive of chronic inflammation. Multiple small (solid) chronic inflammatory nodules in the remaining lungs are highly probable; close CT observation is recommended to rule out mixed metastases. A few chronic inflammations and old lesions in both lungs. c. Slight thickening of the pleura bilaterally. Small amount of effusion in the superior pericardial recess. Calcification of some arterial walls.

2. A few ischemic lesions in the deep bilateral brain regions, with mild age-related brain changes. A few chronic inflammations in the bilateral maxillary sinuses.

3. Small renal calculus in the left kidney. Left renal cyst. Mild prostatic hyperplasia.

4. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulge.

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.
