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, 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.
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 significant abnormalities.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasopharyngeal wall showed no thickening; FDG uptake was not abnormal; the pharyngeal recesses were symmetrical bilaterally; the Eustachian tube openings were not narrowed; the infratemporal and pterygopalatine fossae were structurally normal; the parapharyngeal spaces were clear bilaterally, and FDG uptake was not abnormal.
The palatine tonsils showed physiological uptake bilaterally.
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 was normal in shape and size, with uniform density; FDG uptake was not abnormal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
The interlobular septa of both lungs are thickened, with multiple nodular and patchy areas of increased density, some with blurred margins, most prominent in the right upper and middle lobes.
FDG metabolism is increased, SUVmax = 3.6.
Bilateral pleural effusions are present.
Several lymph nodes are observed in the bilateral hilar regions, pretracheal spaces, para-aortic arch, subcarinal region, and paraesophageal region of the posterior mediastinum, the largest with a short diameter of approximately 0.8 cm.
FDG metabolism is increased, SUVmax = 4.5, and some lymph nodes are calcified.
The cardiac chamber density is lower than that of the myocardium, and there is slight pericardial thickening.
Calcification is present in some arterial walls (including the coronary arteries).
The esophagus is not dilated, and the esophageal wall is not significantly thickened or swollen.
FDG uptake is not increased.
Both breasts are normal, and FDG metabolism is normal.
A slightly low-density lesion with indistinct borders, measuring approximately 2.3 3.0 cm, was observed in the uncinate process of the pancreas.
FDG uptake was elevated, with an SUVmax of 5.2.
The lesion was poorly demarcated from the superior mesenteric artery and posterior splenic vessels.
The splenic artery was thickened with a cast-like low-density shadow.
The spleen was enlarged, with large patches of low-density shadows in the parenchyma.
FDG uptake was absent, but FDG uptake in the capsule was increased, with an SUVmax of 3.6.
The main pancreatic duct and intrahepatic and extrahepatic bile ducts were dilated.
The gallbladder was significantly enlarged, with thickened walls and multiple sac-like protrusions.
The liver had an irregular outline, with multiple low-density shadows within it, the largest measuring approximately 2.5 2.4 cm.
FDG uptake was elevated, with an SUVmax of 4.5.
Several lymph nodes were observed bilaterally in the cardiophrenic angle, posterior to the diaphragmatic crus, at the porta hepatis, and around the pancreatic head.
The largest had a short diameter of approximately 1.0 cm.
FDG uptake was elevated, with an SUVmax of 5.3.
The mesenteric fat space in the abdominal cavity was blurred, and FDG uptake was normal.
A small amount of fluid accumulation in the pelvic cavity.
Several cystic lesions were observed in both kidneys, the largest being approximately 1.1 cm in long diameter; FDG uptake showed no significant abnormalities.
Both adrenal glands were slightly enlarged, with increased FDG uptake on the left side (SUVmax = 3.3).
Gastric distension was poor, with slight thickening of the walls in parts of the gastric body and antrum; FDG uptake was increased (SUVmax = 4.3).
Intestinal distension was unsatisfactory; continuous FDG metabolism in the colon and rectum was increased (SUVmax = 5.9).
Uterine atrophy was observed, with no abnormal FDG metabolism.
No abnormal FDG metabolism was observed in the bilateral adnexa.
Bladder distension was normal, with no obvious positive stones.
Multiple vertebral bodies and adnexa of the sternum and spine, and multiple bone destructions in both iliac bones showed increased FDG metabolism (SUVmax = 5.6).
The spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies, and bulging of the L4/5 and L5/S1 intervertebral discs.
There is air accumulation in the L5/S1 intervertebral disc.

Impression

1. a. A mass in the uncinate process of the pancreas with increased FDG metabolism. Combined with enhanced MRI from our center, pancreatic cancer is highly probable, involving adjacent blood vessels and accompanied by low-level biliary obstruction. Clinical correlation is required. b. Multiple liver metastases. Tumor thrombi in the splenic vascular zone with large-area splenic infarction are highly probable. Multiple bone metastases throughout the body. c. Multiple lymph nodes are visible in the bilateral cardiophrenic angles, posterior diaphragmatic crura, hepatic hilum, and around the pancreatic head. Some have increased FDG metabolism, suggesting possible metastases. Follow-up is recommended. d. Blurred mesenteric fat space in the abdominal cavity, with normal FDG metabolism, suggests possible inflammatory changes. Follow-up is recommended. Small amount of pelvic effusion.

2. Interstitial lung changes with multiple inflammations in both lungs. Post-treatment CT re-examination is recommended to rule out hidden lesions. Small amount of bilateral pleural effusion.

3. Anemia. Slight pericardial thickening. Calcification of some arterial walls (including coronary arteries).

4. Gallbladder diverticulum, chronic cholecystitis. Please combine with ultrasound examination. Bilateral renal cysts. Bilateral adrenal hyperplasia is highly probable.

5. Slight thickening of the walls of part of the gastric body and antrum, increased FDG uptake, suggestive of chronic gastritis; continuous increased FDG metabolism in the colon and rectum, suggestive of inflammatory or physiological uptake. Follow-up gastroscopy and colonoscopy are recommended for the above.

6. Degenerative changes in the spine. L5/S1 intervertebral disc pneumoconiosis. L4/5, L5/S1 intervertebral disc bulge.

7. A few ischemic foci in the deep bilateral brain; senile encephalopathy.

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.
