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 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.
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 small ground-glass nodules were seen in the upper lobes of both lungs and the right middle lobe.
The largest was located in the posterior segment of the left upper lobe, with a CT value of approximately -517 HU, measuring approximately 0.9 0.7 cm, with relatively clear borders; FDG metabolism was normal.
Several solid small nodules were also seen in both lungs, with a long diameter of approximately 0.2?.5 cm, clear borders, and some with increased FDG metabolism (SUVmax = 1.6).
A few punctate and linear lesions were also seen in both lungs; FDG metabolism was normal.
There was a small amount of pleural effusion bilaterally, and partial atelectasis in the lower lobes of both lungs.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal, with slight pericardial thickening.
The cardiac chamber density was lower than that of the myocardium.
The esophagus showed no dilation, no significant thickening or mass in the esophageal wall, and no increased FDG uptake.
Bilateral mammary glands showed dense fibroadenomas with multiple nodular changes; FDG metabolism was normal.
The liver had an irregular outline, with diffuse low-density masses and nodules of varying sizes within the liver, coalescing into clusters, predominantly in the right lobe; FDG metabolism was increased, SUVmax = 12.4.
The main portal vein showed no significant widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder wall was slightly thickened, with multiple irregular dense shadows filling the lumen, the largest being approximately 1.8 cm in long diameter; FDG metabolism was normal.
The pancreas had a normal morphology, with no significant abnormal density shadows in the parenchyma; the main pancreatic duct was not widened; FDG uptake was normal.
The spleen showed no abnormalities in morphology, size, density, or FDG uptake.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows seen in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging shows no obvious abnormalities.
The stomach is poorly distended, with no obvious thickening of the gastric wall, and FDG uptake is not significantly abnormal.
The intestines are poorly distended, with no obvious thickening or mass in the intestinal wall; FDG uptake is physiological.
The uterus is of normal shape, with patchy areas of increased FDG metabolism in the uterine cavity (SUVmax = 4.3).
A cystic lesion is seen in the right adnexa, with a long diameter of approximately 2.0 cm, showing increased FDG metabolism (SUVmax = 11.3).
The bladder is generally distended, with no obvious positive stones seen within.
Multiple enlarged lymph nodes were observed in the prediaphragmatic group, hepatic hilum, portal vena cava space, around the pancreatic head, and para-aortic region.
The largest lymph node had a short diameter of approximately 2.0 cm.
FDG metabolism was elevated, with SUVmax = 10.6.
A small amount of pelvic effusion was present.
The spinal alignment was normal, and the vertebral bodies were intact.
Systemic bone marrow FDG metabolism was normal.

Impression

1. a. Diffuse intrahepatic lesion with increased FDG metabolism, suggestive of malignancy; please refer to pathology. b. Multiple lymph node metastases in the prediaphragmatic group, abdominal cavity, and retroperitoneum. Small amount of pelvic effusion. c. Chronic cholecystitis. Gallstones.

2. a. Ground-glass nodules in the upper lobes of both lungs and the middle lobe of the right lung, with normal FDG metabolism, suggestive of atypical adenomatous hyperplasia. Early lung cancer cannot be ruled out in the apical-posterior segment nodule of the left upper lobe. HRCT follow-up is recommended in 3 months. b. Several small chronic inflammatory nodules (solid) in both lungs, excluding some metastatic tumors; close observation is recommended. A small amount of chronic inflammation and old lesions in both lungs. c. Small amount of pleural effusion bilaterally, partial atelectasis in the lower lobes of both lungs. Slight pericardial thickening. Anemia.

3. Bilateral breast proliferative changes.

4. Physiological uptake in the uterine cavity.

5. Physiological ovarian cyst in the right adnexal region.

6. No abnormalities 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.
