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; no significant abnormalities were observed in FDG uptake.
No widening was observed in the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no significant abnormalities.
No thickening was observed in the paranasal sinus mucosa; the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; the palatine tonsils were symmetrical bilaterally, 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; 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.
Small solid nodules are present in the apical and anterior segments of the left upper lobe and the posterior segment of the right upper lobe, the largest being approximately 0.3 cm in diameter.
FDG uptake is normal.
A few linear lesions are present in both lungs, with normal FDG uptake.
There is no pleural thickening bilaterally, and no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes are seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette is normal.
Some arterial walls show calcification (including the coronary arteries).
The esophagus is not dilated, and the wall is not significantly thickened or swollen; FDG uptake is normal.
No significant masses or nodules are seen in either breast; FDG metabolism is normal.
The liver is normal in shape and size, with smooth borders and no widening of the hepatic fissure.
Multiple cystic lesions are present in the liver, the largest located in the right posterior segment, with a long diameter of approximately 1.6 cm; FDG uptake is normal.
The main portal vein is not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts is observed.
The gallbladder appeared normal in shape and size, with no thickening of the gallbladder wall and no abnormalities in local FDG uptake.
An irregular soft tissue density shadow was observed in the head of the pancreas, with indistinct borders, measuring approximately 2.4*2.5cm.
FDG uptake was increased (SUVmax = 6.3), and the pancreatic duct was dilated.
No abnormal density shadows were observed in the remaining pancreas, with a few surrounding exudates.
FDG uptake was increased (SUVmax = 4.1).
Multiple small lymph nodes were visible around the pancreas, in the retroperitoneum, in the left posterior diaphragmatic crura, and in the mesentery.
The largest had a short diameter of approximately 0.6cm, and FDG metabolism was normal.
No ascites was observed in the abdominopelvic cavity.
The spleen appeared normal in shape, size, density, and FDG uptake.
Both kidneys appeared normal in shape and size.
Multiple small cystic lesions were observed in the renal parenchyma, the largest being located at the lower pole of the right kidney, with a long diameter of approximately 1.2cm.
FDG metabolism was normal.
The renal pelvis, calyces, and ureters were not widened, and FDG uptake was not significantly abnormal.
No significant abnormalities were observed in the bilateral adrenal glands.
Stomach fullness is acceptable, with thickening of the gastric wall in the antrum and slightly increased FDG uptake (SUVmax = 3.2).
Intestinal fullness is unsatisfactory; no masses are observed locally, but FDG uptake is increased in some intestinal segments (SUVmax = 7.8).
Uterus is absent.
No obvious abnormalities are seen in the bilateral adnexa.
Bladder fullness is poor, but no obvious positive stones are seen.
Spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies.
L4/5 and L5/S1 intervertebral disc bulges, with no abnormal FDG uptake.
No abnormal FDG uptake is seen in the entire skeleton.
Subcutaneous calcification is present in the left buttock.
Small patchy FDG uptake is present in the right shoulder periarticular region (SUVmax = 3.5).

Impression

1. A mass in the head of the pancreas with increased FDG metabolism and pancreatic duct dilation suggests pancreatic head cancer complicated by pancreatitis; please correlate with clinicopathology. Reactive hyperplasia of the peripancreatic, retroperitoneal, left posterior diaphragmatic crura, and mesenteric lymph nodes is possible; follow-up is recommended to rule out other possibilities.

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

3. Multiple liver cysts. Small renal cysts. Post-hysterectomy changes.

4. Chronic inflammatory changes in the antrum of the stomach and part of the intestine; please follow up with endoscopy.

5. Degenerative changes in the spine, L4/5 and L5/S1 intervertebral disc bulges. Subcutaneous calcification in the left buttock. Inflammation of the right shoulder.

6. No obvious abnormalities were found on cranial scintigraphy.

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.
