Whole-body 18F-FDG PET/CT scan in a patient with Pancreatic 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 images showed: Normal brain morphology and structure; no abnormal density shadows were seen in the brain parenchyma; and no significant abnormalities were observed in FDG uptake.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical and showed no significant abnormalities.
Thickening of the left maxillary sinus mucosa was observed, but no thickening was observed in the mucosa of the other paranasal sinuses, and the sinus walls were intact.
Nasal septum deviation was observed; no thickening of the nasopharyngeal wall was observed; the palatine tonsils were symmetrical, and FDG uptake was physiological.
The laryngopharynx was normal in morphology and structure.
The parotid and submandibular glands were normal in morphology and density, and FDG uptake was physiological.
The thyroid gland was normal in morphology and size, with uniform density, and FDG uptake was normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, or submental region.
The lung markings are clear.
Multiple solid nodules are present in both lungs, predominantly subpleural, with the largest located in the lateral basal segment of the right lower lobe, approximately 0.6 cm in diameter.
FDG uptake is normal.
A few scattered linear lesions are present in both lungs, with normal FDG uptake.
No pleural thickening is observed bilaterally, and there is no pleural effusion or pneumothorax.
No significantly enlarged lymph nodes are seen in the hilar and mediastinal regions.
The cardiac silhouette is normal.
Calcification is present in some arterial walls (including the coronary arteries).
The esophagus is not dilated, and the wall is not significantly thickened or swollen; FDG uptake is normal.
The liver is normal in shape and size, with smooth borders and no widening of the hepatic fissure.
Multiple small cystic lesions are present in the liver, the largest approximately 1.1 cm in diameter; FDG uptake is normal.
The main portal vein is not significantly widened, and no dilation is seen in the intrahepatic or extrahepatic bile ducts.
The gallbladder is enlarged, but the gallbladder wall is not thickened, and local FDG uptake is normal.
An irregular soft tissue mass in the head of the pancreas, with indistinct borders, measures approximately 5.2*4.1*5.0cm.
Low-density lesions are visible within the mass, with absent FDG uptake and increased FDG uptake in the remaining portion (SUVmax = 10.5).
The boundary between the mass and the adjacent duodenum is indistinct.
The pancreatic duct is dilated, and FDG uptake in the remaining pancreas is unevenly increased (SUVmax = 5.4).
Exudative shadows are seen in the surrounding fat spaces.
Small peripancreatic lymph nodes are visible, the largest with a short diameter of approximately 0.5cm; FDG metabolism is normal.
The spleen shows no abnormalities in morphology, size, density, or FDG uptake.
Both kidneys are normal in morphology and size, with several small cystic lesions in the renal parenchyma, the largest approximately 0.7cm in diameter; FDG metabolism is normal.
High-density shadows are seen in the renal pelvis, calyces, ureters, and bladder.
Bilateral adrenal glands show no significant abnormalities on contrast imaging.
The stomach is adequately distended, with slight thickening of the gastric wall in the antrum and increased FDG uptake (SUVmax = 4.7).
The intestines are not fully full, with a significant amount of residual contents in the intestinal lumen.
No masses were observed in the affected area, and FDG uptake was normal.
The prostate is full, with punctate dense shadows visible within; FDG uptake was not abnormally increased.
Bilateral testicular tunica vaginalis calcifications were present.
The spinal alignment was normal, with some vertebral body margin osteophytes, mild anterior slippage of the L4 vertebral body, and L4/5 and L5/S1 intervertebral disc bulging.
FDG uptake of the entire skeleton was normal.
A subcutaneous fat density shadow measuring approximately 3.4*1.3cm was observed in the left posterior neck, with absent FDG uptake.
A small patch of increased FDG uptake was observed around the left shoulder, with SUVmax=4.0.

Impression

1. A mass in the head of the pancreas with elevated FDG metabolism is suggestive of a malignant tumor, most likely pancreatic cancer with obstructive inflammation; small peripancreatic lymph nodes show no abnormalities in FDG metabolism, follow-up is recommended.

2. Chronic inflammatory nodules in both lungs. A few post-inflammatory lesions in both lungs. Calcification of some arterial walls (including coronary arteries).

3. Multiple liver cysts. Gallbladder effusion.

4. Residual contrast agent in the urinary tract. Small cysts in both kidneys. Benign prostatic hyperplasia with calcification. Calcification foci in the tunica vaginalis of both testes.

5. Physiological uptake or chronic inflammatory changes in the gastric antrum; follow-up with endoscopy is recommended.

6. Degenerative changes in the spine, mild anterior slippage of the L4 vertebral body, L4/5 and L5/S1 intervertebral disc bulges. Subcutaneous lipoma in the left posterior neck. Left shoulder periarthritis.

7. No obvious abnormalities were found on cranial scintigraphy. Chronic inflammation of the left maxillary sinus.

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.
