Whole-body 18F-FDG PET/CT scan in a patient with Liver 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 tomographic images showed:The brain morphology and structure were normal, with no abnormal density shadows in the brain parenchyma, and no significant abnormalities in FDG uptake.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical, with no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed, and FDG uptake was normal.
The palatine tonsils were slightly enlarged bilaterally, with increased FDG uptake (SUVmax = 5.6).
The laryngopharynx morphology and structure were normal.
The parotid and submandibular glands bilaterally had normal morphology and density, with physiological FDG uptake.
The thyroid gland was normal in shape and size, with slightly uneven density, and no abnormalities in FDG uptake.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region.
Increased lung markings were observed bilaterally; several solid micronodules (long diameter less than 0.3 cm) were seen in the right lung, with normal FDG uptake.
A few linear areas of increased density were also observed in both lungs, with normal FDG uptake.
Arc-shaped fluid-density shadows were observed in both pleural cavities, with partial compression of lung tissue in the lower lobes of both lungs.
No pleural thickening was observed bilaterally.
No significantly enlarged lymph nodes were observed in the bilateral hilum; several small lymph nodes were visible in the mediastinum, the largest being approximately 0.5 cm in short diameter, with normal FDG uptake.
The cardiac silhouette was normal.
Calcification of some arterial walls (including coronary arteries) was observed.
The esophagus was not dilated, and no significant thickening or mass was observed in the esophagus wall; no increased FDG uptake was observed.
A large amount of fluid was observed in the abdominal and pelvic cavities, with some tissue structures poorly visualized.
The liver is reduced in size, with disproportionate left and right lobes, irregular liver margins, and a wavy appearance.
The liver fissure is widened.
The liver parenchyma density is uneven, and FDG uptake is uneven (SUVmax = 4.1).
After a delay, the uneven FDG uptake slightly increases (SUVmax = 4.8).
Punctate calcifications are seen in the right lobe of the liver.
The main portal vein is not significantly widened, and there is no dilation of intrahepatic or extrahepatic bile ducts.
Slight thickening of the peritoneum and mesentery is seen in the abdomen and pelvis, but FDG uptake is normal.
Multiple small lymph nodes are visible in the porta hepatis, hiatal space, retroperitoneum, and part of the mesenteric region, the largest being approximately 0.5 cm in short diameter.
Some lymph nodes show slightly increased FDG uptake (SUVmax = 3.0).
The gallbladder is poorly visualized.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct is not widened, and FDG uptake is normal.
Spleen enlarged, parenchymal density and FDG uptake normal.
Kidneys normal in shape and size, no obvious abnormal density shadows seen in the parenchyma, no widening of the renal pelvis, calyces, and ureters bilaterally, punctate high-density shadows seen in the lower calyx of the left kidney, FDG uptake no obvious abnormalities.
Adrenal glands bilaterally normal on contrast.
Stomach generally full, no obvious thickening of the stomach wall, increased FDG uptake in some parts of the stomach wall, SUVmax=3.7.
Intestinal fullness poor, no obvious thickening or mass seen in the intestinal wall, increased FDG uptake in some parts of the intestine, SUVmax=4.9.
Prostate normal in size, homogeneous density, no abnormally increased FDG uptake.
Bladder poorly full, no obvious positive stones seen.
Spinal alignment normal, cervical curvature straightened, some vertebral body margins showing osteophyte formation.
L5/S1 intervertebral disc bulge, FDG uptake showed no abnormalities.

Impression

1. a. Uneven liver density and FDG metabolism; multiple lesions in the liver indicated by an external hospital were not clearly visualized on PET/CT; enhanced MRI is recommended for comprehensive analysis. b. Liver cirrhosis, calcification in the right lobe of the liver. Splenomegaly. Massive ascites. Gallbladder poorly visualized. c. Slight thickening of the peritoneum and mesentery in the abdomen and pelvis; FDG metabolism normal, likely reactive hyperplasia; reactive hyperplasia of small lymph nodes in the porta hepatis, hilar space, retroperitoneum, and part of the mesenteric region. Follow-up is recommended to rule out other complications.

2. a. Chronic inflammatory micronodules in the right lung; follow-up with CT is recommended. A few chronic inflammations and sequelae in both lungs. Bilateral pleural effusion; partial atelectasis in the lower lobes of both lungs. b. Reactive hyperplasia of small mediastinal lymph nodes. Calcification of some arterial walls (including coronary arteries).

3. Possible small kidney stone in the left kidney.

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. Osteophyte formation in some vertebral bodies of the spine, straightening of the cervical curvature. L5/S1 disc bulge.

6. No obvious abnormalities seen on cranial scintigraphy. Chronic inflammation of both palatine tonsils.

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.
