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:The brain morphology and structure were normal, with no abnormal density shadows in the brain parenchyma, and no abnormal FDG uptake.
No widening of the ventricles, sulci, fissures, or cisterns was observed, with no abnormalities in local density or FDG uptake, and no midline shift.
The morphology and outline of both eyeballs were normal, the retrobulbar structures were clear, and FDG uptake was normal.
Slight thickening of the right frontal sinus mucosa was observed, while the mucosa of the other paranasal sinuses was not thickened, and the sinus walls were intact.
No significant thickening of the soft tissue on both sides of the nasopharyngeal wall was observed, the pharyngeal recesses were symmetrical, and FDG uptake was normal.
Both palatine tonsils were full, and FDG uptake was physiological.
The morphology and structure of the laryngopharynx were normal, and the parapharyngeal space was clear.
The parotid and submandibular glands were normal in size, shape, and density, with normal FDG uptake.
The thyroid gland was normal in shape and size, but its density was slightly uneven; FDG uptake was normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, or submental region; FDG uptake was normal.
A few patchy, linear, and solid miliary lesions were observed in both lungs.
Arc-shaped ground-glass opacities were seen in the subpleural region of the lower lobes of both lungs.
Punctate calcifications were seen in the right lower lobe, and a few cystic lucent shadows were seen in the subpleural region of the right lower lobe; FDG uptake was normal.
Slight pleural thickening was observed in some areas; no significant pleural effusion was observed bilaterally.
Small hilar lymph nodes were visible bilaterally, with high density and increased FDG uptake (SUVmax = 3.9).
No enlarged lymph nodes were observed in the mediastinum; FDG uptake was normal.
The heart size was normal.
The liver showed no obvious abnormalities in morphology and size.
Multiple nodular low-density lesions with indistinct borders were observed within the liver parenchyma.
The largest lesion, measuring approximately 14.3 8.0 7.5 cm, was located in the left lobe and contained patchy necrotic low-density lesions.
Increased FDG uptake was observed in the surrounding solid portion (SUVmax = 5.8).
No significant shrinkage was observed in the adjacent capsule.
Mild, widespread dilation of the intrahepatic bile ducts was noted.
Post-cholecystectomy changes were observed.
Multiple enlarged and swollen lymph nodes were observed in the hepatogastric space, hiatal space, and retroperitoneum, the largest measuring approximately 2.2 1.1 cm, with increased FDG uptake (SUVmax = 4.3).
A small amount of pelvic effusion was present.
The pancreatic peripancreatic spaces were clear, with no obvious abnormal density shadows in the parenchyma.
The pancreatic duct was not widened, and no abnormal FDG uptake was observed.
The spleen showed essentially normal morphology and size, with no abnormalities in density or FDG uptake.
Low-density nodular lesions were seen in both adrenal glands, with increased FDG uptake on the left side (SUVmax = 4.1).
Both kidneys were normal in shape and size.
A roughly round low-density lesion approximately 1.2 cm in diameter was seen at the lower pole of the right kidney, with absent FDG uptake.
No obvious abnormal density shadows were seen in the left renal parenchyma, and FDG uptake was not significantly abnormal.
No widening of the renal pelvis, calyces, or ureters was observed bilaterally, and no positive stones were seen locally.
The prostate gland was normal in shape and size, and no focal abnormal increase in FDG uptake was observed.
The bladder was poorly filled, and no positive stones were seen in the lumen.
The esophagus was not dilated, and no obvious thickening or mass was seen in the esophageal wall; FDG uptake was not increased.
The stomach was poorly filled, with slight thickening of part of the gastric wall; FDG uptake was increased (SUVmax = 2.5).
The intestines were unsatisfactoryly filled, with no local masses; FDG uptake was not abnormal.
The lumbar spine is unstable, with osteophyte formation at the margins of some vertebral bodies.
The L3 vertebral body is slightly displaced anteriorly, and the L5 vertebral body is slightly displaced posteriorly.
There are bulging discs at L3/4 and L4/5, and a herniated disc at L5/S1.
No abnormal uptake was observed on FDG.
A small patchy area of increased FDG uptake was seen on the anterolateral aspect of the left femoral neck, with SUVmax = 2.9.

Impression

1. a. Multiple intrahepatic lesions, the largest located in the left lobe with internal necrosis and increased FDG metabolism, suggestive of primary hepatocellular carcinoma with intrahepatic dissemination. b. Multiple lymph node metastases in the hepatogastric space, hilar space, and retroperitoneum. Bilateral adrenal metastases are highly probable. c. Left femoral neck metastasis to be ruled out; please confirm with MRI.

2. Widespread mild dilatation of intrahepatic bile ducts. Post-cholecystectomy changes. Right renal cyst. Small amount of pelvic effusion.

3. Manifestations of chronic gastritis; endoscopic re-examination necessary.

4. A few chronic pulmonary lesions (including miliary foci) and remnants, lower lobular hypostatic effect, paraseptal emphysema in the right lower lobe, reactive hyperplasia of small hilar lymph nodes in both lungs.

5. Degenerative changes in the spine, lumbar vertebral instability, L3/4 and L4/5 disc bulges, and L5/S1 disc herniation.

6. No obvious abnormalities were found on cranial scintigraphy. Chronic inflammation of the right frontal sinus.

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.
