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 scan showed: Normal brain morphology and structure; no abnormal density shadows were seen in the brain parenchyma; no significant abnormalities were observed in FDG uptake.
Widening of the ventricles, sulci, fissures, and cisterns was observed; the ventricles were symmetrical bilaterally, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed; the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; no abnormalities were observed in FDG uptake; the pharyngeal recesses were symmetrical bilaterally; there was no narrowing of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the bilateral parapharyngeal spaces were clear; and no abnormalities were observed in FDG uptake.
The palatine tonsils showed physiological uptake bilaterally.
The laryngopharynx was normal in morphology and structure.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The thyroid gland was normal in morphology and size, with slightly uneven density; no abnormalities were observed in FDG uptake.
Several small lymph nodes were observed in the bilateral deep cervical spaces and submandibular region; no abnormalities in FDG metabolism were observed.
Scattered solid nodules with clear borders, approximately 0.3-0.6 cm in long diameter, were observed in both lungs; FDG uptake was normal.
Multiple cystic lucent shadows were observed in both lungs; calcification was present in the right lung.
No pleural thickening was observed bilaterally; no pleural effusion or pneumothorax was observed bilaterally.
No significantly enlarged lymph nodes were observed in the hilum or mediastinum bilaterally.
Calcification of some arterial walls was observed.
The cardiac silhouette was normal.
No esophageal dilation was observed; no significant thickening or mass was observed in the esophagus; FDG uptake was normal.
The liver showed no significant abnormalities in shape or size; the liver margins were smooth; the hepatic fissure was not widened.
CT scan revealed multiple roundish, slightly hypodense lesions in the liver parenchyma, the largest measuring approximately 4.8*2.7 cm; FDG metabolism was increased; SUVmax = 16.2.
Scattered hypodense lesions were observed in the liver with clear borders and absent FDG uptake; the largest measuring approximately 4.8*3.8 cm.
No significant widening of the main portal vein was observed; no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder appeared normal in shape and size, but the gallbladder wall was thickened, and a soft tissue shadow measuring approximately 1.3*0.9cm was seen within the gallbladder.
FDG metabolism was increased, with an SUVmax of 5.4.
A patchy, slightly low-density shadow measuring approximately 6.4*2.5cm was seen in the pancreatic tail, with indistinct borders from the splenic hilum.
FDG metabolism was increased, with an SUVmax of 7.7.
Both kidneys were normal in shape and size, with scattered low-density lesions in both kidneys.
The lesion had poor FDG uptake, with the largest measuring approximately 0.8cm in long diameter.
The renal pelvis, calyces, and ureters were not widened, and FDG uptake was not significantly abnormal.
Bilateral adrenal gland imaging showed no significant abnormalities.
The stomach was poorly distended, with no significant thickening of the stomach wall and no significant abnormalities in FDG uptake.
The intestines were poorly distended, with increased FDG metabolism in some intestinal segments (SUVmax = 6.1).
The prostate was enlarged, with a transverse diameter of approximately 5.5cm, and punctate calcifications were seen within.
FDG uptake was not abnormally increased.
The bladder was generally full, with no obvious positive stones observed.
Several lymph nodes were seen in the porta hepatis and retroperitoneum, the largest with a short diameter of approximately 0.8 cm, showing increased FDG metabolism (SUVmax = 6.4).
No obvious fluid accumulation was observed in the abdomen or pelvis.
The spinal alignment was normal, with some vertebral body margin osteophytes and some thoracic intervertebral discs showing pneumothorax.
Increased FDG metabolism was observed in the right 3rd and 6th ribs, left iliac crest, left T8 vertebral body, and left pubic bone (SUVmax = 8.3).

Impression

1. a. A slightly low-density mass in the tail of the pancreas with increased FDG metabolism, poorly demarcated from the splenic hilum, highly suggestive of pancreatic cancer; please correlate with clinicopathology. b. Multiple liver metastases. Metastases in the hilar and retroperitoneal lymph nodes. Metastases in the right 3rd and 6th ribs, left T8 vertebral body, left iliac bone, and left pubic bone.

2. Gallbladder wall thickening, soft tissue lesions within the gallbladder with increased FDG metabolism, suggestive of gallbladder adenomyosis; local malignancy to be ruled out; please correlate with pathology.

3. Multiple liver cysts. Small renal cysts.

4. Scattered chronic inflammatory nodules in both lungs. Emphysema in both lungs. Calcification in the right lung. Calcification of some arterial walls.

5. Physiological or inflammatory uptake in some intestinal segments; please correlate with colonoscopy follow-up.

6. Benign prostatic hyperplasia with calcification.

7. Some vertebral osteophytes. Some thoracic intervertebral disc effusion.

8. 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.
