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: The brain morphology and structure were normal; no abnormal density shadows were seen in the brain parenchyma, and FDG uptake was normal.
No widening was observed in the ventricles, sulci, fissures, or cisterns; local density and FDG uptake were normal; and there was no midline shift.
The bilateral eyeballs had normal morphology and outlines; retrobulbar structures were clear; the bilateral optic nerves were symmetrical; and FDG uptake was normal.
No thickening was observed in the paranasal sinus mucosa; the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; there was no stenosis in the bilateral pharyngeal recesses or Eustachian tube openings; the infratemporal fossa and pterygopalatine fossa structures were normal; the bilateral parapharyngeal spaces were clear; and FDG uptake was normal.
FDG uptake in the oropharynx and laryngopharynx was physiological.
No abnormal contrast was observed in the bilateral parotid and submandibular glands.
Thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
Small lymph nodes are seen in the bilateral deep cervical spaces, submandibular region, and submental region; FDG uptake is normal.
Interlobular septa are thickened in both lungs, with scattered diffuse solid nodules.
The largest is located in the posterior basal segment of the right lower lobe, with a long diameter of approximately 0.7 cm and clear borders; some have increased FDG uptake (SUVmax = 1.1).
Scattered linear and patchy hazy shadows are seen in both lungs; FDG uptake is increased (SUVmax = 2.1).
Scattered calcifications are seen in both lungs.
No pleural thickening is seen bilaterally; there is no pleural effusion or pneumothorax bilaterally.
Small lymph nodes are seen in the bilateral hilar and mediastinal regions; some have increased FDG uptake (SUVmax = 4.9).
The cardiac silhouette is normal; myocardial FDG uptake is normal.
No significant thickening or mass is seen in the esophageal wall; FDG uptake is normal.
Both breasts are full in shape, with no abnormal density shadows seen in the fibrous glands, and FDG uptake is normal.
The liver is normal in shape and size, with smooth liver margins and no widening of the liver fissures.
Multiple slightly low-density nodules are seen in the liver parenchyma, the largest being approximately 1.3 cm in length in the right anterior lobe, with indistinct borders, and increased FDG uptake (SUVmax = 7.5).
A cystic lesion approximately 0.7 cm in length is seen in the right lobe of the liver.
The main portal vein is not significantly widened, and no dilation is seen in the intrahepatic or extrahepatic bile ducts.
The gallbladder is normal in shape and size, with no thickening of the gallbladder wall, no positive stones or obvious masses, and no abnormal FDG uptake.
A mass of increased FDG uptake is seen in the tail of the pancreas (SUVmax = 13.4), with an uptake area of approximately 3.7*1.5 cm.
Multiple lymph nodes were observed parapancreatic tail and retroperitoneally, near the aorta, the largest with a short diameter of approximately 0.5 cm.
FDG uptake was increased, SUVmax = 5.8.
Flocculent high-density shadows were seen in the mesenteric space, and linear shadows were seen in the rectouterine pouch, with increased FDG uptake, SUVmax = 1.8.
No significant fluid accumulation was observed in the abdomen or pelvis.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys showed no abnormalities in shape or size; punctate dense shadows were seen in the middle of the left kidney, with no abnormal FDG uptake.
No widening of the renal pelvis, calyces, or ureters was observed; punctate high-density shadows were seen in the left renal calyx.
Both adrenal glands showed no abnormalities in shape or density, with no abnormal FDG uptake.
The stomach was poorly distended, with increased FDG uptake in parts of the gastric wall, SUVmax = 2.1.
Bowel preparation was poor; no obvious masses were seen in the intestinal wall, but FDG uptake was increased in some intestinal segments (SUVmax = 3.9).
The uterus was normal in shape, with no abnormal density shadows and normal FDG uptake.
No abnormal density or FDG uptake was seen in the bilateral adnexa.
The bladder was adequately filled, with no positive stones or obvious masses.
Lumbar sacralization was observed.
The spinal alignment was normal, but FDG uptake was increased in the C5 and T4 vertebral bodies and their appendages, and the L2 vertebral body (SUVmax = 6.6).
Bone density was uneven in the former two vertebral bodies.
Osteophyte formation was observed at the marginal vertebral bodies in some areas, and L3/4 and L4/5 intervertebral disc bulges were present.

Impression

1. a. Massive FDG-promoted lesions in the tail of the pancreas, suggestive of malignancy, pancreatic cancer is the primary consideration. b. Metastasis to the para-tailed, retroperitoneal, and para-aortic lymph nodes. Bone metastases to the C5, T4 vertebral bodies and appendages, and L2 vertebral body. c. Multiple liver metastases and liver cysts. Abdominal and pelvic peritoneal implantation metastases to be ruled out.

2. Multiple solid nodules in both lungs, some with increased FDG metabolism, some metastases are the primary consideration; close CT observation is recommended. Interstitial changes in both lungs with scattered inflammation and remnants (including calcifications). Reactive hyperplasia of the hilar and mediastinal lymph nodes in both lungs. Bilateral breast hyperplasia.

3. Calcification in the middle of the left kidney, left renal calculus, no obvious space-occupying lesions; please combine with contrast-enhanced MRI images from other hospitals for comprehensive analysis.

4. Increased FDG metabolism in parts of the stomach wall and intestines, possibly due to physiological uptake or chronic inflammation; please follow up with endoscopy.

5. Lumbar sacralization. Spinal degenerative changes. L3/4 and L4/5 intervertebral disc bulge.

6. No obvious abnormalities seen on cranial scintigraphy.

7. Uneven thyroid density; ultrasound follow-up recommended. Reactive hyperplasia of cervical lymph nodes.

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.
