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 images showed: Normal brain morphology and structure; no abnormal density shadows were seen in the brain parenchyma; FDG uptake was normal.
No widening was observed in the ventricles, sulci, fissures, or cisterns; local density and FDG uptake were normal; and midline structure shift was normal.
The bilateral eyeballs had normal morphology and outline; retrobulbar structures were clear; and FDG uptake was normal.
No thickening of the paranasal sinus mucosa was observed; the sinus walls were intact.
No significant thickening of the soft tissue on both sides of the nasopharynx was observed; the bilateral pharyngeal recesses were symmetrical; and FDG uptake was normal.
The base of the tongue and both palatine tonsils were full; and FDG uptake was physiological.
The laryngopharynx had normal morphology and structure; the parapharyngeal space was clear.
The bilateral parotid and submandibular glands had normal size, shape, and density; and FDG uptake was physiological.
The thyroid gland had normal morphology and size; density was slightly uneven; and FDG uptake was normal.
Bilateral deep cervical interspace and submandibular lymph nodes showed increased FDG uptake in some lymph nodes in the right deep cervical interspace (SUVmax = 2.6).
A few patchy shadows were seen in the middle and lower lobes of the right lung, and a solid miliary lesion was seen in the posterior segment of the right upper lobe; FDG uptake was not abnormal.
No significant thickening of the pleura or pleural effusion was observed bilaterally.
No significantly enlarged lymph nodes were seen in the hilum and mediastinum bilaterally; FDG uptake was not significantly increased.
The heart size was normal.
A large, multilocular cystic lesion measuring approximately 17.9 12.7 18.8 cm was seen in the right lobe of the liver, with indistinct margins.
No obvious mural nodules or calcifications were observed in the internal septa; however, FDG uptake was increased in some septa and cyst walls (SUVmax = 9.4).
Multiple low-density nodules and masses were observed within the remaining liver parenchyma, with indistinct borders.
The larger nodules showed patchy necrosis in the center, while the largest, located in the lower segment of the right posterior lobe, measured approximately 9.1 5.8 cm.
The solid portion showed increased FDG uptake (SUVmax = 7.4).
No dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder appeared normal in shape and size, with no thickening of the gallbladder wall, no positive stones or obvious masses, and normal FDG uptake in the gallbladder fossa.
The peripancreatic spaces were clear, and the pancreatic duct was not widened.
A low-density mass measuring approximately 8.1 5.7 5.5 cm was observed in the tail of the pancreas, with visible borders and heterogeneous density.
FDG uptake was increased (SUVmax = 7.1), with compression changes observed in the adjacent gastric wall and left adrenal gland.
Several enlarged lymph nodes were observed posteriorly and inferiorly at the left renal hilum, the largest being approximately 2.6 cm in diameter, with increased FDG uptake (SUVmax = 7.3).
A small amount of fluid was observed in the abdominopelvic cavity.
Multiple tortuous blood vessels were observed in the abdominal cavity.
The spleen was of normal shape and size, with no abnormalities in density or FDG uptake.
The bilateral adrenal glands were of normal shape, size, and density, with no abnormalities in local FDG uptake.
The bilateral kidneys were of normal shape and size, with no obvious abnormal density shadows in the renal parenchyma, and no obvious abnormalities in FDG uptake.
The renal pelvis, calyces, and ureters were not widened, and no positive stones were observed locally.
The prostate was of normal shape and size, and no focal abnormal increases in FDG uptake were observed.
The bladder was poorly filled, and no positive stones were observed in the lumen.
The esophagus was not dilated, and no obvious thickening or mass was observed in the esophageal wall; no increased FDG uptake was observed.
The stomach was well filled, with increased FDG uptake at the cardia (SUVmax = 4.9); the gastric antrum showed slight thickening of the gastric wall, but no abnormalities in FDG uptake were observed.
The intestines were unsatisfactoryly filled, with no local masses observed, and no abnormalities in FDG uptake were observed.
The sternum shows expansion, with rough cortical bone and uneven internal density.
Small cystic low-density lesions and patchy ground-glass opacities are observed, with some areas showing sclerosis at the margins.
FDG uptake is increased, with SUVmax = 3.1.
The spinal alignment is normal, with some vertebral body margins showing osteophyte formation.
No abnormal FDG uptake was observed.
Internal fixation of the left clavicle is in progress.

Impression

1. a. Low-density mass in the tail of the pancreas with increased FDG metabolism; multiple low-density lesions in the liver parenchyma with increased FDG metabolism; enlarged retroperitoneal lymph nodes with increased FDG metabolism. All of these suggest malignancy, with a high probability of pancreatic cancer (possibly pancreatic carcinoma) accompanied by multiple metastases; metastases cannot be ruled out. b. A large, multilocular cystic lesion in the right lobe of the liver, with increased FDG metabolism in some septa and cyst walls, strongly suggests malignancy; enhanced MRI analysis is recommended. c. Multiple tortuous vessels in the abdominal cavity, indicating obstructed venous return. Small amount of effusion in the abdominopelvic cavity. d. Expansile changes in the sternum with mixed bone density and slightly increased FDG metabolism, suggesting possible fibrous dysplasia of bone; metastases need to be ruled out.

2. Chronic miliary lesions in the upper lobe of the right lung; a small amount of chronic inflammation in the middle and lower lobes of the right lung.

3. Possible physiological uptake at the gastric cardia; contracted state of the gastric antrum.

4. Vertebral osteophyte formation in the spine. Internal fixation of the left clavicle with metal fixation underway.

5. No obvious abnormalities were found on cranial scintigraphy. Reactive hyperplasia of bilateral cervical lymph nodes was observed.

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.
