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.
The ventricles, sulci, fissures, and cisterns were not widened; the ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical, with no obvious abnormalities.
The left maxillary sinus mucosa was thickened, but the sinus wall was intact.
The nasopharyngeal wall was not thickened, 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 morphology and structure were normal.
The 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 masses and nodules of varying sizes were seen in both lungs, the largest being located in the posterior segment of the left upper lobe and the apical segment of the right upper lobe, measuring approximately 3.93.4cm and 4.43.5cm respectively, with partially indistinct borders and lobulated edges; FDG metabolism was increased, SUVmax=10.2.
Multiple scattered linear and patchy shadows were seen in both lungs; FDG metabolism was normal.
No pleural thickening was seen bilaterally; there was no pleural effusion or pneumothorax bilaterally.
Multiple enlarged lymph nodes were seen in the bilateral hilar regions, pre-vasculature space, pretracheal space, para-aortic arch, aortopulmonary window, and subcarinal region; the largest had a short diameter of approximately 1.3cm; FDG metabolism was increased, SUVmax=4.5.
The heart is enlarged, and some arterial walls are calcified (including the coronary arteries).
The esophagus is not dilated, and the wall is not significantly thickened or lumpy; FDG uptake is not increased.
Post-operative left breast cancer surgery; no abnormal FDG metabolism was observed in the surgical area.
The right breast is normal; FDG metabolism is normal.
The liver is normal in shape and size; the liver margins are smooth; the liver fissure is not widened; no significant abnormal density shadows were seen in the liver parenchyma on plain CT scan; FDG uptake is normal.
The main portal vein is not significantly widened; no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder is normal in shape and size; the gallbladder wall is slightly thickened; patchy dense shadows are seen in the lumen, with a long diameter of approximately 0.8 cm; FDG metabolism is normal.
An irregular low-density mass measuring approximately 6.6 2.7 cm was observed in the body and tail of the pancreas.
FDG metabolism was increased, with an SUVmax of 5.6.
The mass exhibited heterogeneous density and was closely adhered to the adjacent stomach wall.
No abnormalities were observed in the head and neck of the pancreas.
The spleen showed no abnormalities in morphology, size, density, or FDG uptake.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters were not widened, and FDG uptake was not significantly abnormal.
No obvious abnormalities were observed in the bilateral adrenal glands.
The intestines were poorly filled, with no obvious thickening or mass in the intestinal wall; FDG uptake was physiological.
The uterus had a normal shape and no abnormal FDG metabolism was observed.
No abnormal FDG metabolism was observed in the bilateral adnexa.
The bladder was generally full, with no obvious positive stones observed.
No enlarged lymph nodes were observed in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulges.
Systemic bone marrow FDG metabolism was normal.

Impression

1. A mass in the body and tail of the pancreas with increased FDG metabolism suggests a malignant tumor (possibly pancreatic cancer). Please correlate with clinicopathology.

2. Multiple inflammatory foci in both lungs; multiple masses and nodules in both lungs with increased FDG metabolism suggest a high probability of metastatic tumors. Please monitor clinical progress. Reactive hyperplasia of the hilar and mediastinal lymph nodes is possible, but metastasis cannot be ruled out.

3. Postoperative left breast cancer surgery; no signs of tumor recurrence were observed in the surgical area.

4. Enlarged cardiac silhouette; calcification of some arterial walls (including coronary arteries). Further specialist clinical examination is recommended.

5. Chronic cholecystitis; gallstones.

6. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulges.

7. No abnormalities were found on cranial scintigraphy. Chronic inflammation of the left maxillary sinus.

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.
