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, with no abnormal density shadows in the brain parenchyma, and no abnormal FDG uptake.
There was no widening of the ventricles, sulci, fissures, or cisterns; local density and FDG uptake were normal, and there was no midline shift.
The bilateral eyeballs had normal morphology and outline; the retrobulbar structures were clear, and FDG uptake was normal.
The left ethmoid and maxillary sinus mucosa showed slight thickening, while the mucosa of the remaining paranasal sinuses showed no thickening, and the sinus walls were intact.
No significant thickening of the soft tissue on both sides of the nasopharyngeal walls was observed; the bilateral pharyngeal recesses were symmetrical, and FDG uptake was normal.
The oropharynx and laryngopharynx had normal morphology and structure, and the parapharyngeal spaces were clear.
The bilateral parotid and submandibular glands showed normal size, shape, and density, and FDG uptake was physiological.
Thyroid gland is normal in shape and size, with uneven density; FDG uptake is normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region; FDG uptake is normal.
Scattered multiple solid nodules of varying sizes are seen in both lungs, with clear borders; some are irregular in shape, with increased FDG uptake (SUVmax = 2.2).
A few patchy, linear shadows and calcifications are seen in both lungs; FDG uptake is normal.
Right-sided pleural effusion with partial atelectasis of the right lower lobe.
No significant pleural effusion is seen on the left side.
Heart size is normal.
Liver size is disproportionate; liver margins are irregular; hepatic fissure is slightly widened.
The liver parenchyma shows heterogeneous density, with scattered multiple low-density nodules and masses, predominantly in the right lobe accompanied by some punctate and patchy high-density lesions, predominantly in the right anterior lobe with localized decreased FDG metabolism, and increased FDG uptake in other lesions (SUVmax = 9.6).
Multiple enlarged lymph nodes are visible in the hepatogastric space, hepatic hilum, hilar space, retroperitoneal space near the great vessels and pancreas, posterior to the bilateral diaphragmatic crura, left lower quadrant mesentery, bilateral common iliac vessels, right anterior diaphragm, right knee joint, posterior mediastinum near the esophagus, right lower pulmonary ligament, right hilum, right internal mammary chain, superior mediastinal vascular space, and bilateral supraclavicular fossa.
These lymph nodes have indistinct borders, some fused into clusters, and some internally necrotic, with increased FDG uptake (SUVmax = 11.0).
There is a large amount of fluid in the abdominopelvic cavity, with slight thickening of the peritoneum in some areas; FDG uptake is not abnormal.
No dilation of intrahepatic or extrahepatic bile ducts is observed.
The gallbladder is not clearly visualized; FDG uptake in the gallbladder fossa is normal.
The peripancreatic spaces are clear, with no obvious abnormal density shadows in the parenchyma.
The pancreatic duct is not widened, and FDG uptake is normal.
The spleen is enlarged, but FDG uptake is normal.
A soft tissue nodule with a long diameter of approximately 1.4 cm is seen in the left adrenal gland, with increased FDG uptake (SUVmax = 9.6).
The right adrenal gland shows no abnormalities in shape, size, or density, and localized FDG uptake is normal.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows in the renal parenchyma, and FDG uptake is normal.
The renal pelvis, calyces, and ureters are not widened, and no positive stones are seen locally.
The prostate gland shows no abnormalities in shape and size, with punctate calcifications inside, and no focal abnormal increase in FDG uptake.
A nodular FDG uptake shadow with an SUVmax = 8.5 and a long diameter of approximately 1.3 cm is seen in the penile root region.
Hydrocele in the right testis.
Bladder distension is poor, no positive stones were found in the cavity.
Esophageal dilation was not observed, and no significant thickening or mass was seen in the esophageal wall; FDG uptake was not increased.
Stomach distension is poor, with slight thickening of part of the stomach wall; FDG uptake is increased, SUVmax=3.2.
Intestinal distension is unsatisfactory, no local mass was seen, and FDG uptake was normal.
Soft tissue nodules were seen in the medullary cavity of the right humerus and upper femur; FDG uptake is increased, SUVmax=12.0.
Increased FDG uptake was observed in both scapulae, some ribs on both sides, multiple vertebrae and their appendages, bones of the pelvis, and upper femurs on both sides, most notably in the left acetabulum, accompanied by soft tissue mass formation, SUVmax=10.6, with an uptake range of approximately 7.84.6cm.
Scoliosis, misalignment of vertebrae, osteophyte formation at the margins of some vertebrae, slight anterior displacement of the L5 vertebra with bilateral pars interarticularis fractures.
Multiple posterior ribs on the right side are distorted.

Impression

1. a. After interventional treatment for liver cancer: Tumor activity in the right lobe of the liver is suppressed; multiple space-occupying lesions in the remaining liver with significantly increased FDG metabolism are considered metastatic tumors with tumor activity. b. Multiple lymph node metastases throughout the body (as mentioned above). Multiple bone metastases throughout the body (as mentioned above). Multiple lung metastases. Left adrenal gland metastasis. High probability of metastasis in the penile root region. c. Slight thickening of the peritoneum in some areas, likely due to edema; metastasis to be ruled out. Liver cirrhosis, splenomegaly, and large amounts of effusion in the abdominal and pelvic cavities.

2. Poor gastric filling; possible inflammatory uptake of part of the gastric wall; gastroscopy re-examination is necessary if needed.

3. Prostatic calcification. Right testicular hydrocele.

4. A few chronic lesions and sequelae in both lungs. Right pleural effusion with partial atelectasis in the lower lobe of the right lung.

5. Scoliosis, osteophyte formation at the margins of some vertebral bodies, grade I anterior slippage of the L5 vertebral body with bilateral pars interarticularis fractures. Post-fracture changes of multiple posterior ribs on the right side.

6. Cranial scintigraphy showed no obvious abnormalities. Minor chronic inflammation of the left ethmoid and maxillary sinuses.

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.
