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: Brain morphology and structure were normal, with patchy low-density shadows in the deep cerebral regions bilaterally; FDG uptake was not significantly abnormal.
The ventricular system was slightly enlarged, with widening of the sulci, fissures, and cisterns; the ventricles were symmetrical bilaterally, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no significant abnormalities.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasopharyngeal wall showed no thickening; FDG uptake was normal; the pharyngeal recesses were symmetrical bilaterally; the Eustachian tube openings were not narrowed; the infratemporal and pterygopalatine fossae were structurally normal; the parapharyngeal spaces were clear bilaterally, and FDG uptake was normal.
The palatine tonsils showed physiological uptake bilaterally.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The laryngopharynx showed no abnormalities in morphology and structure.
The thyroid gland is normal in shape and size, with uniform density, and FDG uptake is normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region, and FDG metabolism was normal.
Striped and patchy high-density shadows were seen in the upper lobes and posterior segments of the lower lobes of both lungs.
Scattered solid nodules, cords, and calcifications were seen in both lungs.
The pleura was thickened and adhered bilaterally, and FDG uptake was normal.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
Partial calcification was observed in the walls of the aorta and coronary arteries.
No esophageal dilation was observed, and no significant thickening or mass was observed in the esophageal wall; FDG uptake was not increased.
Both breasts are relatively dense, with calcification in the upper outer quadrant of the left breast; FDG metabolism was normal.
The liver showed no obvious abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
Multiple low-density nodules and masses were observed within the liver, with some fused into a patchy mass in the left lateral lobe, measuring approximately 6.4 3.2 cm.
FDG uptake was increased, with an SUVmax of 12.4.
Multiple lymph nodes were observed in the hepatogastric space, hepatic hilum, and pancreatic head region, the largest with a short diameter of approximately 0.5 cm.
FDG metabolism was increased, with an SUVmax of 5.4.
Two soft tissue nodules with relatively clear borders were observed in the left anterior pelvic region, the larger one with a long diameter of approximately 3.3 cm.
FDG metabolism was increased, with an SUVmax of 4.5.
No significant fluid accumulation was observed in the abdomen or pelvis.
The gallbladder was of acceptable shape, with increased density within the lumen, but no abnormalities in local FDG uptake.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct was not widened, and FDG uptake was not significantly abnormal.
The spleen is of normal shape, with a punctate dense shadow visible on the medial side.
FDG uptake is normal.
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 normal.
Bilateral adrenal gland imaging is normal.
Stomach distension is poor, with slightly elevated FDG uptake in some gastric walls (SUVmax = 2.0).
Intestinal distension is poor, with no obvious thickening or mass in the intestinal wall.
FDG uptake is increased in some intestinal segments (SUVmax = 3.3).
The uterus is normal in shape, with no abnormal density shadows and no abnormally increased FDG uptake.
No abnormal FDG metabolism is seen in the bilateral adnexa.
Bladder distension is normal, with no obvious positive stones seen.
Slight scoliosis, osteophyte formation at the margins of some vertebral bodies, slight anterior displacement of the L4 vertebral body, bulging of the L3/4, L4/5, and L5/S1 intervertebral discs, and pneumothorax within the L5/S1 intervertebral disc.
Small nodular low-density shadows with sclerotic margins are seen in the right iliac bone; FDG uptake is normal.

Impression

1. a. Multiple low-density lesions in the liver with increased FDG metabolism, suggestive of malignancy, possibly primary or metastatic. Please combine clinical findings with enhanced MRI for comprehensive analysis. b. Multiple lymph node metastases in the hepatogastric space, hepatic hilum, and pancreatic head region. Two nodules in the left anterior pelvic region with increased FDG metabolism, suggestive of implantation metastasis.

2. Old fibrocalcifications in both lungs; please follow up with CT. Partial calcification of the aorta and coronary artery walls. Bilateral breast hyperplasia, with calcification in the upper outer quadrant of the left breast; ultrasound follow-up is recommended.

3. Calcifications in the spleen. Possible causes include cholestasis or cholesterol crystals in the gallbladder; ultrasound follow-up is recommended.

4. Increased FDG metabolism in parts of the gastric wall and intestinal tract, suggestive of physiological or chronic inflammatory changes; please combine clinical findings with endoscopic follow-up.

5. Scoliosis with degenerative changes, mild anterior slippage of the L4 vertebral body. L3/4, L4/5, and L5/S1 intervertebral disc bulges, with pneumatosis and degeneration of the L5/S1 intervertebral disc. Benign bone disease of the right iliac bone.

6. Bilateral deep lacunar infarcts, age-related brain changes.

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.
