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 with both hands raised, extending from the top of the skull to the upper thigh.
The scan showed: Normal brain morphology and structure; no abnormal density shadows were seen in the brain parenchyma; no significant abnormalities were observed in FDG uptake.
No widening was observed in the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical and showed no significant abnormalities.
No thickening was observed in the paranasal sinus mucosa; the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; no abnormalities were observed in FDG uptake; the pharyngeal recesses were symmetrical; there was no narrowing of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the parapharyngeal spaces were clear bilaterally; and no abnormalities were observed in FDG uptake.
No abnormalities were observed in FDG uptake in the oropharynx and laryngopharynx.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The thyroid gland was normal in shape and size, with uniform density; and no abnormalities were observed in FDG uptake.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region; FDG uptake was normal.
Multiple solid nodules were observed in both lungs, with relatively clear borders; the largest nodule's long diameter was approximately 0.3 cm; FDG uptake was normal.
Scattered linear shadows were observed in both lungs; FDG uptake was normal.
The pleura was slightly thickened bilaterally, but there was no pleural effusion or pneumothorax.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal.
The liver was full in shape, containing a large mass, mostly located in the right lobe, presenting as a cluster of multiple nodules with heterogeneous internal density; FDG uptake was increased; the cross-section was approximately 16.4 cm 12.9 cm, SUVmax = 12.8; portal vein visualization was indistinct.
The gallbladder was of acceptable shape, with heterogeneous increased density within the lumen; FDG uptake was normal.
The pancreas was normal in shape, with no significantly abnormal density shadows in the parenchyma; the main pancreatic duct was not widened; FDG uptake was normal.
Spleen morphology, size, density, and FDG uptake were normal.
Kidneys were normal in shape and size, with multiple small, round, high-density shadows in both renal calyces, the largest approximately 0.5 cm in long diameter.
A small, round, high-density shadow, approximately 1.0 cm in long diameter, was also seen in the upper segment of the left ureter, with dilation and hydronephrosis of the ureter and renal pelvis above it.
FDG uptake was not significantly abnormal.
Adrenal glands showed no significant abnormalities on contrast imaging.
Esophageal dilation was not observed, and the esophageal wall showed no significant thickening or mass; FDG uptake was not increased.
Stomach distension was poor, and the gastric wall showed no significant thickening; FDG uptake was not significantly abnormal.
Intestinal distension was poor, and the intestinal wall showed no significant thickening or mass; FDG uptake was physiological.
Prostate morphology was acceptable, with punctate calcifications observed; FDG uptake was not abnormally increased.
Bladder distension was normal, and no obvious positive stones were observed.
No enlarged lymph nodes were observed in the abdomen, pelvis, or retroperitoneal region; FDG uptake was not abnormal.
No obvious fluid accumulation was observed in the abdomen or pelvis.
The spine showed slight scoliosis, with osteophyte formation at the margins of some vertebral bodies, and L3/4 and L4/5 intervertebral disc bulging.
FDG uptake was normal.
No abnormal FDG uptake was observed in any of the bones examined.

Impression

1. a. Large, mixed-density mass in the liver, with increased FDG metabolism, suggestive of hepatocellular carcinoma. b. Portal vein visualization is indistinct.

2. Multiple chronic inflammatory micronodules in both lungs, with a few post-inflammatory lesions in both lungs. Slight pleural thickening bilaterally.

3. Cholestasis in the gallbladder; follow-up ultrasound is recommended. Multiple kidney stones in both kidneys, a stone in the upper left ureter with hydronephrosis of the ureter and renal pelvis above it. Calcification in the prostate.

4. Slight scoliosis with osteophyte formation in the spine. L3/4 and L4/5 intervertebral disc bulges.

5. No abnormalities were found on cranial imaging.

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.
