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; midline shift was not observed.
Both eyes were symmetrical, with no obvious abnormalities.
The ethmoid sinus mucosa was thickened bilaterally, but the mucosa of the remaining paranasal sinuses was not thickened, and the sinus walls were intact.
The nasal septum was slightly deviated, but the nasopharyngeal wall was not thickened; 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, and the bilateral parapharyngeal spaces were clear; FDG uptake was normal.
The palatine tonsils showed physiological uptake bilaterally.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
The thyroid gland is enlarged with uneven density, containing multiple low-density nodules, some with calcifications.
The largest nodule has a long diameter of approximately 1.3 cm, with increased FDG uptake (SUVmax = 2.7).
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
The lung markings are clear.
Multiple solid nodules of varying sizes with well-defined borders are present in both lungs.
The largest nodule is located in the posterior basal segment of the left lower lobe, with a long diameter of approximately 2.2 cm.
FDG uptake is increased (SUVmax = 3.4).
Scattered linear lesions are present in both lungs, with normal FDG uptake.
The pleura is thickened bilaterally, but there is no pleural effusion or pneumothorax.
Multiple lymph nodes are seen in the pretracheal space, para-aortic arch, aortopulmonary window, and subcarinal region.
The largest nodule has a short diameter of approximately 0.8 cm, with increased FDG uptake (SUVmax = 3.1).
The cardiac silhouette is normal.
Calcification is present in some arterial walls (including the coronary arteries).
The esophagus showed no dilation, no significant thickening or mass in the esophageal wall, and no increased FDG uptake.
The liver showed no significant abnormalities in shape or size, with smooth liver margins, no widening of the hepatic fissure, slightly decreased liver density, a dense nodule in the right posterior lobe, and several cystic lesions within the liver, the largest located in the right posterior lobe, approximately 1.5 cm in diameter; FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape or size, no thickening of the gallbladder wall, and no abnormalities in localized FDG uptake.
The pancreas was normal in shape, with no significant 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 are normal in shape and size.
A dense nodule in the right renal calyx, approximately 0.4 cm in diameter, is present.
Several small cystic lesions are present in the renal parenchyma, the largest approximately 0.6 cm in diameter.
FDG metabolism is normal.
No widening of the renal pelvis, calyces, or ureters is observed, and FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging is normal.
Gastric distension is poor, with slight thickening of the antral wall and mildly increased FDG uptake (SUVmax = 2.5).
Intestinal distension is unsatisfactory, with considerable residual contents in the intestinal lumen.
FDG uptake is increased in some intestinal segments (SUVmax = 7.5).
The prostate is enlarged with calcifications.
The prostate density is uneven, and FDG uptake is increased (SUVmax = 3.8).
Multiple enlarged lymph nodes are present in the bilateral pelvic walls, bilateral iliac vessels, presacral region, and retroperitoneum.
The largest is located beside the right iliac vessel, with a short diameter of approximately 2.7 cm.
FDG uptake is increased (SUVmax = 3.6).
The bladder is adequately filled, with an inserted urinary catheter.
Patchy dense shadows are seen within the bladder.
The right inguinal canal is widened, with intestinal herniation observed.
Calcifications are present in the left testicular tunica vaginalis.
Multiple bone destructions are observed in the right 7th and 9th ribs, left 5th rib, multiple vertebral bodies and appendages of the spine, sacrum, bilateral iliac bones, and right pubic tubercle, with the most pronounced destruction in the sacrum.
FDG uptake is increased (SUVmax = 20.3).
The spinal canals and sacral canals at the T7 and T11 levels are involved, with flattening of the T11 vertebral body.
The spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies and multiple intervertebral disc bulges.

Impression

1. a. Benign prostatic hyperplasia with calcification, prostatic mass with increased FDG metabolism, suggestive of prostate cancer. 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), involvement of the spinal canal and sacral canal at the T7 and T11 levels, pathological fracture of the T11 vertebra. Multiple lung metastases.

2. Scattered post-inflammatory lesions in both lungs. Reactive hyperplasia of mediastinal lymph nodes. Calcification of some arterial walls (including coronary arteries).

3. Mild fatty liver, calcification in the right lobe of the liver, hepatic cysts.

4. Right renal calculus, small renal cysts in both kidneys. Bladder calculus, catheter in place. Right inguinal hernia. Calcification of the tunica vaginalis in the left testis.

5. Chronic inflammatory changes or physiological uptake in the gastric antrum and part of the intestine; please follow up with endoscopy.

6. Degenerative changes in the spine, multiple intervertebral disc bulges.

7. Multiple thyroid nodules, some with calcification, increased FDG metabolism, suggestive of nodular goiter.

8. Age-related brain, deep lacunar infarcts. Bilateral chronic ethmoid sinusitis.

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.
