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: Brain morphology and structure were normal, with punctate, slightly low-density shadows in the deep brain regions; FDG metabolism was normal.
The ventricles, sulci, fissures, and cisterns were widened, but local density and FDG uptake were normal; there was no midline shift.
Both eyes were symmetrical with no obvious abnormalities.
There was poor pneumatization of the right mastoid process.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasal septum was deviated, but the nasopharyngeal wall was not thickened; FDG uptake was normal.
The pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear with no abnormal FDG uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The oropharynx and laryngopharynx showed no abnormalities in morphology and structure.
The right lobe of the thyroid gland is enlarged, containing several low-density nodules, the largest being approximately 1.9 cm in long diameter, with increased FDG uptake (SUVmax = 2.1).
The left lobe shows uneven density, with no abnormal FDG uptake.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
Both lungs show clear lung markings, with several solid nodules in each lung, the largest approximately 0.3 cm in diameter, with no abnormal FDG uptake.
Multiple air-filled cavities are present in both lungs, along with scattered calcifications and linear foci, with no abnormal FDG uptake.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal.
Some arterial walls showed calcification (including the coronary arteries).
The esophagus was not dilated, and the esophageal wall showed no significant thickening or mass, with no increased FDG uptake.
The liver's morphology and size are normal, with smooth borders and no widening of the hepatic fissure.
Liver density is decreased; CT value: 44 HU.
Calcification is present in the right lobe of the liver, along with several small cystic lesions approximately 0.5 cm in diameter.
FDG uptake is normal.
The main portal vein is not significantly widened, and no dilation is observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder's morphology and size are normal, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas is normal in morphology, with punctate dense shadows in the pancreatic head.
The main pancreatic duct is not widened, and FDG uptake is normal.
The spleen's morphology, size, density, and FDG uptake are normal.
Both kidneys are normal in shape and size.
Several cystic lesions are present in the renal parenchyma, the largest being in the right kidney, approximately 3.5 cm in diameter, with absent FDG uptake.
Another high-density lesion, approximately 0.7 cm in diameter, is also seen in the right kidney.
No widening of the renal pelvis, calyces, or ureter is observed, and FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging shows no significant abnormalities.
Stomach distension is poor, with slight thickening of the cardia, part of the gastric body, and antrum walls, and mildly increased FDG uptake (SUVmax = 2.2).
Intestinal distension is unsatisfactory, with no obvious space-occupying lesions observed; intestinal uptake is physiological.
Bladder distension is poor, with no obvious positive stones observed.
A small amount of hydrocele is present in both testes.
The prostate is full and uneven in density.
Soft tissue density shadows with increased FDG uptake are seen on the left side (SUVmax = 17.6), with an uptake area of approximately 4.1*2.3*3.1cm.
The boundary between some of these areas and the adjacent bladder is indistinct.
Multiple enlarged lymph nodes are present on both pelvic walls, bilaterally to the iliac vessels, presacral region, and retroperitoneum.
The largest is located beside the left iliac vessel, with a short diameter of approximately 2.1cm, showing increased FDG uptake (SUVmax = 15.7).
Multiple bone destructions are observed in the right scapula, right 5th and 10th ribs, left 5th and 6th ribs, multiple vertebral bodies and appendages of the spine, bones of the pelvis, and the upper segment of the left femur.
The most significant destruction is located in the T12 vertebral body, showing increased FDG uptake (SUVmax = 14.2).
The T6 and L1 vertebral bodies are flattened.
The spinal alignment is normal, with some vertebral body margin osteophytes.
L4/5 and L5/S1 intervertebral disc bulges are present.
Schmorl's nodes at the lower margin of the T12 and L1 vertebral bodies.

Impression

1. a. Benign prostatic hyperplasia, prostatic mass with increased FDG metabolism, suggestive of prostate cancer; please correlate with PSA and pathology. b. Multiple lymph node metastases in the bilateral pelvic walls, bilateral iliac vessels, presacral region, and retroperitoneum. c. Multiple bone metastases throughout the body (see description for details). Pathological fractures of the T6 and L1 vertebrae.

2. Chronic inflammatory micronodules in both lungs; CT follow-up is recommended. Bilateral emphysema, scattered post-inflammatory lesions in both lungs. Calcification of some arterial walls (including coronary arteries).

3. Fatty liver, calcification in the right lobe of the liver, small hepatic cysts. Calcification in the head of the pancreas.

4. Bilateral renal cysts (partially complex cyst in the right kidney). Small amount of hydrocele in both testes.

5. Chronic inflammatory changes in part of the gastric wall; please follow up with endoscopy.

6. Degenerative changes in the spine, L4/5 and L5/S1 intervertebral disc bulges. Schmorl's nodes at the lower margins of the T12 and L1 vertebral bodies.

7. Enlargement of the right thyroid lobe with several low-density nodules, mildly elevated FDG metabolism, suggestive of nodular goiter; please follow up with ultrasound.

8. Age-related brain changes, deep lacunar infarcts in the brain. Right sclerotic mastoid process.

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.
