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: Brain morphology and structure were normal, with punctate, slightly low-density shadows in the deep brain regions; FDG metabolism was normal.
The ventricles, sulci, fissures, and cisterns were widened, but local density and FDG uptake were normal; there was no midline shift.
Both eyes were symmetrical with no obvious 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 normal.
The 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 palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The laryngopharynx showed no abnormalities in morphology and structure.
Focal FDG uptake is increased in the right inferior alveolar fossa, SUVmax=4.6.
The thyroid gland is normal in shape and size, with uneven density; FDG uptake is not abnormal.
No enlarged lymph nodes are seen in the bilateral deep cervical spaces or submandibular region.
Lung markings are disordered, with multiple solid nodules, plaques, calcifications, and linear lesions, most prominent in the lung apex.
Some lesions show increased FDG uptake, SUVmax=3.0.
Lung translucency is increased bilaterally, with multiple air-filled cavities and scattered linear lesions; FDG uptake is not abnormal.
Partial pleural thickening is present bilaterally, but there is no pleural effusion or pneumothorax.
Lymph nodes are visible in the bilateral hilar, pretracheal, para-aortic arch, aortopulmonary window, and subcarinal regions; the largest is located in the right hilum, some with calcification, short diameter approximately 0.8cm, with increased FDG uptake, SUVmax=2.9.
Cardiac silhouette is normal.
Calcification of some arterial walls (including coronary arteries).
No esophageal dilation, wall thickening, or mass was observed; FDG uptake was not increased.
The liver showed no significant abnormalities in shape or size; liver margins were smooth; the hepatic fissure was not widened; plain CT scan showed no significant abnormal density shadows in the liver parenchyma; FDG uptake was normal.
No significant widening of the main portal vein was observed.
A soft tissue nodule in the head of the pancreas, with indistinct borders, measures approximately 2.2*2.0cm, with increased FDG uptake (SUVmax=8.4).
An irregular cystic-solid mass in the body of the pancreas, with indistinct borders, measures approximately 6.3*3.7cm, with unevenly increased FDG uptake (SUVmax=8.6).
The superior mesenteric vein is involved.
The gallbladder is enlarged, and there is extensive dilation of the intrahepatic and extrahepatic bile ducts and pancreatic ducts.
The pancreatic tail is atrophied with unevenly increased FDG uptake (SUVmax=8.9).
The peripancreatic fat space is poorly visualized.
Peripancreatic and abdominal mesenteric lymph nodes are visible, the largest having a short diameter of approximately 1.0cm, with increased FDG uptake (SUVmax=3.8).
The spleen's morphology, size, density, and FDG uptake are normal.
Both kidneys are normal in shape and size, with multiple dense nodules in both renal calyces, the largest being in the right kidney, with a long diameter of approximately 1.1 cm.
No widening of the renal pelvis, calyces, or ureter is observed, and FDG uptake is not significantly abnormal.
The left adrenal gland is enlarged with increased FDG uptake (SUVmax = 2.3), while the right adrenal gland shows no significant abnormalities on imaging.
The gastrointestinal tract contains a large amount of contents and residual gas, with details poorly visualized.
The walls of the cardia, part of the gastric body, and antrum are slightly thickened, with increased FDG uptake (SUVmax = 2.2).
Intestinal uptake is physiological.
The prostate is full, with punctate dense shadows inside; FDG uptake is not abnormally increased.
The bladder is poorly filled, with no obvious positive stones.
Overall bone density is decreased, the spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies, and L4/5 and L5/S1 intervertebral disc bulging.
A high-density lesion, approximately 0.9 cm in diameter, is present in the left pubic tubercle.
Uneven FDG uptake in the bone marrow is observed throughout the body, with SUVmax = 3.6.

Impression

1. Pancreatic mass with increased FDG metabolism, suggestive of pancreatic cancer with biliary obstruction and obstructive pancreatitis. Please correlate with clinicopathology. Peripancreatic and mesenteric lymph nodes show increased FDG metabolism, possibly indicating metastasis. Please correlate with clinical findings.

2. a. Multiple solid nodules, plaque-like lesions, calcifications, and linear lesions in both lungs, some with increased FDG metabolism, suggestive of pulmonary tuberculosis. Some are slightly mobile; follow-up CT is recommended. b. Chronic bronchitis with bilateral emphysema. Scattered post-inflammatory lesions in both lungs. Partial pleural thickening bilaterally. Reactive hyperplasia of hilar and mediastinal lymph nodes bilaterally. Calcification of some arterial walls (including coronary arteries).

3. Left adrenal hyperplasia. Bilateral renal calculi. Benign prostatic hyperplasia with calcification.

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

5. Osteoporosis, degenerative changes in the spine, L4/5 and L5/S1 intervertebral disc bulge. Left pubic tubercle bony island. Unevenly increased FDG metabolism throughout the medullary cavity, likely due to reactive proliferative changes; please correlate with clinical findings.

6. Age-related brain, deep lacunar infarcts; please correlate with MRI. Right inferior alveolar alveolitis.

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.
