Whole-body 18F-FDG PET/CT scan in a patient with Gallbladder 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: The brain morphology and structure were normal; no abnormal density shadows were seen in the brain parenchyma, and FDG uptake was not significantly abnormal.
The ventricles, sulci, fissures, and cisterns were not widened; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical and without 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 pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the parapharyngeal spaces were clear with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
Thyroid gland: Normal in shape and size, with slightly uneven density; FDG uptake not abnormal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
Multiple diffuse solid nodules of varying sizes were observed in both lungs, the largest being approximately 1.5 cm in long diameter; FDG metabolism was increased, SUVmax = 9.4.
No pleural thickening was observed bilaterally; no pleural effusion or pneumothorax was observed bilaterally.
Multiple enlarged lymph nodes were observed in the left hilum and mediastinum, the largest being approximately 1.1 cm in short diameter; FDG metabolism was increased, SUVmax = 11.4.
No abnormalities were observed in the cardiac silhouette.
No esophageal dilation was observed; no significant thickening or mass was observed in the esophageal wall; FDG uptake was not increased.
No obvious abnormalities were observed in both breasts; FDG metabolism was not abnormal.
The gallbladder is poorly visualized, with an irregular, low-density mass in the gallbladder area.
The mass is heterogeneous in density, has indistinct borders, and involves surrounding liver parenchyma, measuring approximately 9.3*7.2*7.1cm.
FDG metabolism is elevated, with an SUVmax of 18.4.
Multiple roundish low-density nodules and masses are observed within the liver parenchyma, the largest approximately 6.0cm in diameter, with elevated FDG metabolism and an SUVmax of 16.6.
Cystic lesions are also seen within the liver.
Multiple enlarged lymph nodes are present in the porta hepatis, hepatogastric space, retroperitoneum, and localized superior mesenteric region, the largest approximately 1.0cm in short diameter, with elevated FDG metabolism and an SUVmax of 13.5.
Multiple soft tissue nodules are present in the pelvic cavity, the largest approximately 2.3*1.5cm, with elevated FDG metabolism and an SUVmax of 13.0.
Some intrahepatic bile ducts are dilated.
The pancreatic duct in the head of the pancreas is dilated, but FDG uptake is not significantly abnormal.
Spleen morphology, size, density, and FDG uptake were normal.
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.
Bilateral adrenal glands showed no obvious abnormalities on contrast imaging.
Stomach distension was poor, with no obvious thickening of the stomach wall, and FDG uptake was not significantly abnormal.
Intestinal distension was poor, with increased FDG metabolism in the rectum and ileocecal region (SUVmax = 5.4).
Small bulges were seen in the uterus, and an intrauterine device was visualized; FDG uptake was not abnormally increased.
Both ovaries were enlarged, with increased FDG metabolism (SUVmax = 9.9).
Bladder distension was normal, and no obvious positive stones were seen.
No obvious fluid accumulation was seen in the abdomen or pelvis.
A soft tissue nodule, approximately 1.1 cm in long diameter, was observed subcutaneously in the right buttock.
FDG metabolism was normal.
Spinal alignment was normal, and systemic bone marrow FDG metabolism was normal.

Impression

1. a. Irregular low-density mass in the gallbladder area, multiple intrahepatic lesions, elevated FDG metabolism, suggestive of malignancy, likely gallbladder cancer with multiple intrahepatic metastases; please correlate with clinicopathology. b. Multiple metastatic tumors in both lungs. Multiple lymph node metastases in the left hilum, mediastinum, hepatic hilum, hepatogastric space, retroperitoneum, and local superior mesenteric region. Multiple implantation metastases in the pelvic cavity. Bilateral ovarian metastases are highly probable.

2. Dilatation of some intrahepatic bile ducts. Dilatation of the pancreatic duct in the head of the pancreas. Liver cysts.

3. Elevated FDG metabolism in the rectum and ileocecal region, suggestive of physiological or inflammatory uptake; please correlate with colonoscopy follow-up.

4. Uterine fibroids, intrauterine device visible. Subcutaneous inflammatory nodule in the right buttock.

5. 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.
