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

Under fasting conditions, an intravenous injection of 18F-FDG was administered, followed by rest.
Whole-body PET/CT imaging revealed the following: Brain morphology and structure were normal; no abnormal density shadows were observed within the brain parenchyma, and FDG uptake was normal.
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 obvious abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
The nasal septum was slightly deviated; the nasopharyngeal wall was not thickened, and FDG uptake was normal.
The pharyngeal recesses were symmetrical bilaterally, and there was no stenosis of the Eustachian tube openings.
The infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear, with no abnormal FDG uptake.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The oropharynx and laryngopharynx showed no abnormalities in morphology and structure.
Thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
Lung markings are clear bilaterally; multiple solid nodules with clear borders are present in both lungs, the largest being located in the apical segment of the right upper lobe, with a long diameter of approximately 0.8 cm; FDG uptake is slightly increased, SUVmax = 1.4; other FDG metabolism is normal.
Scattered linear lesions are present in both lungs; FDG uptake is normal.
Small amount of pleural effusion is present bilaterally.
Multiple small mediastinal lymph nodes are present, the largest with a short diameter of approximately 1.1 cm; FDG uptake is normal.
Cardiac silhouette is normal.
Calcification of some arterial walls (including coronary arteries) is present.
The esophagus is not dilated; no significant thickening or mass is observed in the esophageal wall; FDG uptake is normal.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissures.
Diffuse low-density nodules and masses were observed within the liver, with indistinct borders; the largest measuring approximately 4.7*3.7cm.
FDG uptake was increased, with an SUVmax of 9.0.
Several cystic lesions were also observed in the remaining liver, the largest measuring approximately 2.6*2.3cm, with absent FDG uptake.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape and size, but the gallbladder wall was thickened, and dense nodules were observed within the gallbladder, with a long diameter of approximately 0.9cm.
Local FDG uptake was not abnormal.
The pancreas body and tail are thickened with a low-density mass, poorly defined borders, and uneven density, measuring approximately 6.4*4.2*5.7cm.
FDG uptake is increased (SUVmax = 6.2).
The mass is poorly demarcated from the adjacent stomach wall and splenic hilum.
No significant dilation of the pancreatic duct is observed.
Patchy FDG uptake is present in the pancreatic body and tail (SUVmax = 9.3).
Extensive peritoneum thickening is present.
Multiple soft tissue nodules are observed in the greater omentum and mesentery of the abdominopelvic cavity, the largest being approximately 1.4cm in diameter, with increased FDG uptake (SUVmax = 3.5).
Abdominal and pelvic effusion is present.
The spleen's morphology, size, density, and FDG uptake are normal.
A soft tissue density nodule, approximately 1.1cm in diameter, is present adjacent to the spleen; FDG uptake is normal.
Both kidneys are normal in morphology and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is normal.
Bilateral adrenal gland imaging showed no obvious abnormalities.
Stomach distension was poor, with slight thickening of the cardia, part of the gastric body, and antrum walls, and increased FDG uptake (SUVmax = 2.6).
Intestinal distension was unsatisfactory, but intestinal uptake was physiological.
The prostate was of normal size, containing dense nodules approximately 0.3 cm in diameter, with no abnormally increased FDG uptake.
Bladder distension was adequate, with no obvious positive stones.
Multiple bone lesions were observed in the L4 vertebral body, the left L5 adnexa, the left sacrum, and the left iliac bone, most notably at the L4 vertebral body, with increased FDG uptake (SUVmax = 4.7).
Low-density lesions were found in the muscles adjacent to the left spinous processes of L4 and L5, with increased FDG uptake (SUVmax = 4.8), measuring approximately 2.6*2.3*6.3 cm.
The spinal alignment is normal, with some vertebral body margin osteophytes, and L4/5 and L5/S1 intervertebral disc bulges.
There is subcutaneous calcification in the left buttock.

Impression

1. a. A mass in the body and tail of the pancreas with elevated FDG metabolism, suggestive of pancreatic cancer; please correlate with clinicopathology. b. Diffuse liver metastases. Multiple metastases in the greater omentum and mesentery of the abdominopelvic cavity, with abdominopelvic effusion. c. Multiple bone metastases in the L4 vertebral body, left L5 adnexa, left sacrum, and left iliac bone. Intramuscular metastases in the left paramuscular region of the L4 and L5 spinous processes.

2. Multiple solid nodules in both lungs, some with slightly elevated FDG metabolism, suggestive of inflammatory nodules; CT follow-up is recommended to rule out other possibilities. Scattered post-inflammatory lesions in both lungs. Small amount of pleural effusion bilaterally. Reactive hyperplasia of mediastinal lymph nodes. Calcification of some arterial walls (including coronary arteries).

3. Liver cysts. Chronic cholecystitis, gallstones. Accessory spleen. Prostatic calcifications.

4. Chronic inflammatory changes in part of the gastric wall; please follow up with endoscopy.

5. Degenerative changes in the spine, with L4/5 and L5/S1 intervertebral disc bulges. Subcutaneous calcifications in the left buttock.

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.
