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, and resting, a whole-body PET/CT scan was performed.
The whole-body scan showed:Normal brain morphology and structure, with punctate low-density shadows in the deep cerebral regions bilaterally; FDG uptake was not significantly abnormal.
Some ventricles, sulci, fissures, and cisterns showed widening; local density and FDG uptake were normal; midline structure shift was normal.
Normal eyeball morphology and contours bilaterally; clear retrobulbar structures; symmetrical optic nerves bilaterally; FDG uptake was not significantly abnormal.
No thickening of the paranasal sinus mucosa was observed; sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; FDG uptake was normal; bilateral pharyngeal recesses were symmetrical; Eustachian tube openings were not narrowed; the infratemporal fossa and pterygopalatine fossa structures were normal; bilateral parapharyngeal spaces were clear; FDG uptake was normal.
Bilateral palatine tonsils were full; FDG uptake was physiological.
Laryngopharyngeal morphology and structure were normal.
No abnormal imaging was observed in the bilateral salivary glands.
The thyroid gland is normal in shape and size, with uniform density; FDG uptake was normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region; FDG uptake was normal.
The chest is symmetrical.
Multiple ground-glass nodules are seen in both lungs, some with indistinct borders, approximately 0.4-0.6 cm in length; FDG uptake was normal.
Multiple solid miliary nodules are seen in the right upper lobe and left lower lobe; a few linear opacities are seen in both lungs; calcifications are seen in the right lower lobe.
An air-filled cavity is seen in the right middle lobe.
The trachea is midline, and the trachea and segmental bronchi are patent.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions; FDG uptake was not significantly increased.
No pleural thickening was observed bilaterally; there was no pleural effusion or pneumothorax bilaterally.
The cardiac silhouette was normal.
Calcification of some arterial walls (including coronary arteries).
No esophageal dilation, wall thickening, or masses were observed; FDG uptake was not increased.
The liver showed no significant abnormalities in shape or size; the liver margins were smooth, and the hepatic fissures were not widened.
A nodular area of increased FDG uptake was observed in the left lateral lobe of the liver, with a delayed SUVmax of 7.9 and a long axis of approximately 1.2 cm.
Multiple cystic lesions were observed in the liver parenchyma, the largest located in the right lobe with a long axis of approximately 1.8 cm; FDG uptake was not abnormal.
The main portal vein showed no significant widening; no dilation of intrahepatic or extrahepatic bile ducts was observed.
Multiple lymph nodes were observed in the porta hepatis, hilar space, and retroperitoneum; the largest had a short axis of approximately 0.7 cm, and some showed increased FDG uptake, with an SUVmax of 4.5.
No significant fluid accumulation was observed in the abdomen or pelvis.
The gallbladder was shrunken, containing nodular dense shadows; the gallbladder wall was thickened and rough; FDG uptake was not abnormal.
The pancreas appears normal in morphology, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct is not widened, and FDG uptake is normal.
The spleen appears normal in morphology and size, density, and FDG uptake.
Both kidneys appear normal in morphology and size.
A cystic lesion with a long diameter of approximately 3.9 cm is seen in the left kidney, with absent FDG uptake.
The renal pelvis, calyces, and ureters are not widened, and no positive stones are seen within them.
Both adrenal glands appear normal in morphology and density, and FDG uptake is normal.
The stomach is poorly filled, with increased FDG uptake in some gastric walls (SUVmax = 3.3).
Bowel preparation is poor; no obvious masses are seen in the intestinal wall, but increased FDG uptake in some intestinal segments (SUVmax = 4.3).
The prostate gland appeared normal in shape and size, with a transverse diameter of approximately 4.4 cm.
Calcifications were observed in the prostate tissue.
FDG uptake was not significantly increased.
The bladder was poorly filled, but no obvious positive stones were observed.
The spinal alignment was normal, with some vertebral body margin osteophytes, and L3/4, L4/5, and L5/S1 intervertebral disc bulges.
Nuchal ligament calcification was present.
FDG uptake was increased around both hip joints, with SUVmax = 4.2.

Impression

1. a. Nodular hypermetabolic foci on FDG in the left lateral lobe of the liver, suggestive of a neoplastic lesion; enhanced MRI is recommended for further examination. Multiple liver cysts. b. Reactive hyperplasia of the hilar lymph nodes, hilar space, and retroperitoneal lymph nodes is highly probable; follow-up is recommended to rule out other possibilities.

2. a. Multiple ground-glass nodules in both lungs, FDG metabolism normal, suggestive of chronic inflammatory nodules or atypical adenomatous hyperplasia; annual follow-up with HRCT is recommended. b. Chronic inflammatory nodules (solid) in the right upper lobe and left lower lobe. Pulmonary fibrosis, calcification in the right lower lobe. Emphysema in the right middle lobe. Partial arteriosclerosis (including coronary arteries).

3. Gallstones, chronic cholecystitis. Left renal cyst. Prostatic calcification; follow-up with PSA is recommended.

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. Spinal degeneration. L3/4, L4/5, and L5/S1 intervertebral disc bulges. Bilateral hip periarthritis.

6. Bilateral deep lacunar infarcts, senile encephalopathy.

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.
