Whole-body 18F-FDG PET/CT scan in a patient with Prostate 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: Normal brain morphology and structure, with punctate slightly low-density shadows in the deep brain regions; no abnormalities were observed in FDG metabolism.
Widening of the ventricles, sulci, fissures, and cisterns was observed, but local density and FDG uptake were normal; no midline shift was observed.
Bilateral eyeballs were symmetrical with no obvious abnormalities.
Thickening of the left maxillary sinus mucosa was observed, but thickening was not observed in the mucosa of the other paranasal sinuses; the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; both palatine tonsils were symmetrical, and FDG uptake was physiological.
The laryngopharynx was normal in morphology and structure.
Bilateral parotid and submandibular glands were normal in morphology and density, with physiological FDG uptake.
The right vocal cords were relaxed, with no abnormal FDG uptake.
The thyroid gland was normal in morphology and size, with uniform density; FDG uptake was normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, or submental region.
The lung markings are clear.
Several small solid nodules, approximately 0.2-0.3 cm in diameter, are present in both lungs; no abnormal FDG uptake was observed.
A few air-filled cavities are visible in the subpleural region of the right lung apex.
Scattered linear lesions are present in both lungs; no abnormal FDG uptake was observed.
Bilateral pleural thickening is present, but there is no pleural effusion or pneumothorax.
Small lymph nodes are visible pretracheal, posterior to the vena cava, at the aortic window, para-aortic arch, and below the carina; the largest has a short diameter of approximately 0.8 cm, and increased FDG uptake (SUVmax = 2.5).
The cardiac silhouette is normal.
The cardiac chamber density is slightly lower than that of the myocardium, and some arterial walls (including the coronary arteries) show calcification.
The esophagus is not dilated, and the wall is not significantly thickened or swollen; no increased FDG uptake was observed.
The liver is normal in shape and size, with smooth borders and no widening of the hepatic fissure.
Plain CT scan shows no significant abnormal density shadows in the liver parenchyma; no abnormal FDG uptake was observed.
The main portal vein is not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts is observed.
The gallbladder showed no abnormalities in shape or size, and the gallbladder wall was not thickened.
Local FDG uptake was normal.
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 normal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size.
A low-density lesion containing fat was seen at the upper pole of the right kidney, with a long diameter of approximately 2.0 cm.
No FDG uptake was observed.
Several cystic lesions were present in the parenchyma of the remaining two kidneys, the largest of which was approximately 1.3 cm in diameter.
FDG metabolism was normal.
The renal pelvis, calyces, and ureters were not widened, and FDG uptake was normal.
Bilateral adrenal gland imaging showed no obvious abnormalities.
The stomach was adequately filled, with slight thickening of the gastric cardia, fundus, and antrum walls.
FDG uptake was increased, with SUVmax = 5.3.
Intestinal filling was unsatisfactory.
No local masses were seen, and FDG uptake was normal.
The bladder was poorly filled, with thickening and roughening of the right bladder wall, the thickest part being approximately 1.3 cm.
FDG metabolism was normal.
Bilateral inguinal canal widening was observed, and there was a small amount of hydrocele in both testes.
A soft tissue mass measuring approximately 4.4*3.9*4.0 cm was visible in the prostate, with unevenly increased FDG uptake (SUVmax = 9.4), involving the right epididymis, and its boundary with the adjacent bladder was indistinct.
Multiple lymph nodes were visible in the bilateral iliac vessels, retroperitoneum, and bilateral posterior diaphragmatic crura, the largest with a short diameter of approximately 1.2 cm, showing increased FDG uptake (SUVmax = 7.8).
The spinal alignment was normal, with osteophyte formation at the margins of some vertebral bodies, and L4/5 and L5/S1 intervertebral disc bulging.
Increased FDG uptake was observed in the left hip periarticular region (SUVmax = 3.7).
Bone destruction or high-density lesions were visible on the right scapula, the left transverse process of T11, and the right side of the L2 vertebral body.
FDG uptake was increased, with SUVmax=6.0, most notably at the L2 vertebral body.

Impression

1. a. Prostatic mass with elevated FDG metabolism, consistent with prostate cancer; multiple lymph node metastases bilaterally to the iliac vessels, retroperitoneum, and bilateral posterior diaphragmatic crura. b. Bone metastases to the right scapula, left transverse process of T11, and right side of L2 vertebral body.

2. Thickening and roughening of the right bladder wall, with normal FDG metabolism, suggestive of chronic inflammation; further specialist examination is required.

3. Chronic inflammatory nodules in both lungs. Paraseptal emphysema in the right upper lobe, with a few post-inflammatory lesions in both lungs. Pleural thickening bilaterally. Reactive hyperplasia of mediastinal lymph nodes. Mild anemia, with partial calcification of arterial walls (including coronary arteries).

4. Bilateral renal cysts, with angiomyolipoma of the right upper pole of the kidney to be ruled out. Bilateral inguinal hernias are possible. Small amount of hydrocele in both testes.

5. Chronic gastritis.

6. Degenerative changes in the spine, with L4/5 and L5/S1 intervertebral disc bulges. Left hip periarthritis.

7. Age-related brain abnormalities, deep lacunar infarcts; MRI follow-up recommended. Chronic inflammation of the left maxillary sinus. Right vocal cord laxity.

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.
