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: A few punctate low-density shadows were seen in the deep bilateral brain regions, and punctate fat-density foci were seen in the midline region.
FDG uptake was not significantly abnormal.
The ventricles, sulci, fissures, and cisterns were widened, with symmetrical bilateral ventricles and no midline shift.
The bilateral eyeballs were symmetrical and showed no significant abnormalities.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasopharyngeal wall showed no thickening, and FDG uptake was not abnormal.
The bilateral pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear with no abnormal FDG uptake.
The bilateral palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx were normal.
Thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
Multiple solid nodules were seen in both lungs, approximately 0.2-0.5 cm in long diameter, with clear borders; FDG metabolism was normal.
A few punctate and linear lesions were also seen in both lungs; FDG metabolism was normal.
No pleural thickening was seen bilaterally; no pleural effusion or pneumothorax was observed bilaterally.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal.
Some arterial walls showed calcification (including the coronary arteries).
No esophageal dilatation was seen; no significant thickening or mass was seen in the esophagus; FDG uptake was normal.
Both breasts were normal; FDG metabolism was normal.
The liver showed no obvious abnormalities in shape or size, with smooth liver margins and no widening of the hepatic fissure.
Plain CT scan showed no obvious abnormal density shadows in the liver parenchyma, and FDG uptake was normal.
The main portal vein showed no obvious widening.
The gallbladder showed no abnormalities in shape or size, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas body presented as a full, dense mass, approximately 5.1 3.2 cm in size, with increased FDG metabolism (SUVmax = 4.5).
Splenic vessels were involved, and the pancreatic tail was atrophied.
The mesenteric fat space was blurred with linear shadows, showing mildly increased FDG metabolism (SUVmax = 2.3).
Multiple irregular soft tissue nodules were observed in the greater omentum, subpyloric antrum of the stomach, right paracolic gutter, subcapsular region of the spleen, sigmoid mesentery, and rectouterine pouch, the largest measuring approximately 2.3 1.5 cm, with increased FDG metabolism (SUVmax = 5.9).
Spleen morphology, size, density, and FDG uptake were normal.
A cystic lesion was seen in the left kidney, approximately 0.4 cm in long diameter, with slightly elevated density; FDG metabolism was normal.
The right kidney was normal in shape and size; no obvious abnormal density shadows were seen in the parenchyma; no widening of the renal pelvis, calyces, or ureter was seen; FDG uptake was normal.
Bilateral adrenal gland imaging showed no obvious abnormalities.
Stomach distension was poor; no obvious thickening of the stomach wall was seen; FDG uptake was normal.
Intestinal distension was poor; no obvious thickening or mass was seen in the intestinal wall; FDG uptake was physiological.
Uterus shape was normal; no abnormal FDG metabolism was seen.
No abnormal FDG metabolism was seen in the bilateral adnexa.
Bladder distension was normal; no obvious positive stones were seen.
No obvious fluid accumulation was seen in the abdomen or pelvis.
The spinal alignment is normal, with some vertebral body margin osteophytes, and L4/5 and L5/S1 intervertebral disc herniation with pneumoconiosis and degeneration.
Bilateral acromioclavicular joint FDG uptake is increased, SUVmax = 3.7.
Systemic bone marrow FDG metabolism is normal.

Impression

  1. a. A mass in the pancreatic body with increased FDG metabolism, suggestive of pancreatic cancer, with invasion of splenic vessels. b. Extensive peritoneal seeding metastases in the abdominopelvic cavity. c. Mesenteric panniculitis.

  2. Several small, solid, chronic inflammatory nodules in both lungs. A few chronic inflammatory lesions and old lesions in both lungs. Calcification of some arterial walls (including coronary arteries).

  3. A complex small cyst in the left kidney.

  4. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc herniation with pneumoconiosis and degeneration. Bilateral acromioclavicular arthritis.

  5. A few ischemic lesions in the deep bilateral brain regions. Small lipoma in the midline of the brain.

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.
