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: A few punctate low-density shadows were seen in the deep bilateral cerebral regions; no abnormal density shadows were seen in the remaining brain parenchyma.
FDG uptake was normal.
The ventricles, sulci, fissures, and cisterns were widened; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no obvious 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 bilaterally, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The laryngopharynx showed no abnormalities in morphology or structure.
The thyroid gland is normal in shape and size.
A low-density nodule with clear borders, approximately 1.9 cm in diameter, is seen in the right lobe.
FDG uptake is normal.
No enlarged lymph nodes are seen in the bilateral deep cervical spaces or submandibular region.
A large soft tissue mass, approximately 9.5 6.8 cm in size, with lobulated margins, is seen in the right lower lobe near the hilum.
FDG metabolism is increased, SUVmax = 10.2.
The right middle and lower lobe bronchus is obstructed, with distal consolidation.
Multiple solid micronodules, approximately 0.2?.4 cm in long diameter, with clear borders, are seen in both lungs.
FDG metabolism is normal.
A few cystic lucent shadows are seen in the upper lobes of both lungs.
Scattered patchy opacities and linear foci are also seen in both lungs.
FDG metabolism is normal.
Thickening of the right parasternal pleura and right lower pleura is observed, with increased FDG metabolism (SUVmax = 5.5).
A small amount of pleural effusion is present in the right side.
Multiple enlarged lymph nodes were observed in the right hilum, pretracheal space, aortic window, and below the carina, the largest measuring approximately 3.6 cm in short diameter.
FDG metabolism was increased, with SUVmax = 7.5.
The cardiac silhouette appeared normal.
Calcification was observed in some arterial walls (including the coronary arteries).
The esophagus showed no dilation, wall thickening, or masses, and FDG uptake was not increased.
The liver's shape and size were normal, with smooth borders and no widening of the hepatic fissures.
Multiple cystic lesions were observed within the liver, the largest measuring approximately 1.0 cm in long diameter, with absent FDG uptake.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts.
The gallbladder's shape and size were normal, with no wall thickening and no abnormal local FDG uptake.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no significant abnormal FDG uptake.
Spleen morphology, size, density, and FDG uptake were normal.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters were not widened, and FDG uptake was not significantly abnormal.
Bilateral adrenal gland imaging showed no obvious abnormalities.
Stomach distension was poor, with no obvious thickening of the stomach wall, and FDG uptake was not significantly abnormal.
Intestinal distension was poor, with no obvious thickening or mass in the intestinal wall; FDG uptake was physiological.
FDG metabolism at the anal orifice was increased, SUVmax = 6.9.
The prostate was full in shape, with a transverse diameter of approximately 5.4 cm, and punctate calcifications were observed internally; no abnormal FDG metabolism was observed.
Bladder distension was normal, with no obvious positive stones.
No enlarged lymph nodes were observed in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No obvious fluid accumulation was observed in the abdominal or pelvic cavities.
Osteophyte formation at the margins of some vertebral bodies, lumbar instability, L4/5 and L5/S1 intervertebral disc bulging, and L5/S1 intervertebral disc pneumoconiosis.
Uneven bone density in the right ilium, upper left femur, and left 6th rib, with increased FDG metabolism and SUVmax=5.3.

Impression

1. a. A mass in the lower lobe of the right lung, with increased FDG metabolism, suggestive of central lung cancer with obstructive atelectasis. Multiple lymph node metastases in the right hilum and mediastinum. b. Metastasis to the right parasternal pleura and right lower pleura. Small amount of pleural effusion on the right side. c. Heterogeneous bone density in the right iliac bone, upper femur of the left side, and left 6th rib, with increased FDG metabolism, suggesting a high probability of bone metastasis; further specialist examination is recommended. d. Several small, solid, chronic inflammatory nodules in both lungs. Mild emphysema in the upper lobes of both lungs. Scattered chronic inflammation and old lesions in both lungs.

2. A few ischemic lesions in the deep bilateral brain regions; senile cerebral encephalopathy; MRI is recommended to rule out other possibilities.

3. A low-density nodule in the right lobe of the thyroid gland, with normal FDG uptake, suggestive of benignity; follow-up ultrasound is recommended.

4. Calcification of some arterial walls (including coronary arteries). Multiple liver cysts. Hemorrhoids. Benign prostatic hyperplasia with calcification.

5. Degenerative changes in the spine. Lumbar instability, L4/5 and L5/S1 disc bulging, L5/S1 disc pneumothorax.

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.
