Whole-body 18F-FDG PET/CT scan in a patient with Lung 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; a slightly low-density nodule approximately 1.3 cm in length was observed in the sellar region, with increased FDG uptake (SUVmax = 11.4).
Patchy low-density shadows were seen in the deep cerebral regions bilaterally, and nodular near-cerebrospinal fluid density shadows were seen in the right basal ganglia.
No widening was observed in the ventricles, sulci, fissures, or cisterns; local density and FDG uptake were normal; and there was no midline shift.
The bilateral eyeballs showed normal morphology and outline; retrobulbar structures were clear; the bilateral optic nerves were symmetrical; and FDG uptake was not significantly abnormal.
The right maxillary sinus mucosa was thickened, but the sinus wall was intact.
The nasopharyngeal wall was not thickened; FDG uptake was normal; the bilateral pharyngeal recesses were symmetrical; the Eustachian tube openings were not narrowed; the infratemporal fossa and pterygopalatine fossa structures were normal; the bilateral parapharyngeal spaces were clear; and FDG uptake was normal.
The bilateral palatine tonsils were full and showed physiological FDG uptake.
No abnormalities were observed in the morphology and structure of the laryngopharynx.
No abnormal contrast was observed in the bilateral salivary glands.
The thyroid gland was normal in shape and size, with uniform density, and FDG uptake was normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region, and FDG uptake was normal.
A solid nodule measuring approximately 2.2*2.4cm was observed in the right middle lobe, with lobulated and spiculated margins, and traction on the adjacent pleura; FDG uptake was increased, SUVmax=17.0.
A large patchy high-density shadow was observed in the anterior-lateral basal segment of the right lower lobe, surrounded by patchy hazy shadows; FDG uptake was increased, SUVmax=8.0, and dilated bronchioles were visible within.
Multiple solid nodules, plaques, and calcifications were observed in the upper and lower lobes of both lungs, with slight FDG uptake; the mediastinum and main trachea were pulled to the right.
Multiple solid miliary nodules were observed in both lungs, with no abnormal FDG uptake.
Scattered linear shadows and air-filled cavities were observed in both lungs.
Multiple lymph nodes were observed in the right hilum, paratracheal region of the superior mediastinum, pretracheal region, posterior to the vena cava, aortic window, and subcarinal region.
The largest lymph node had a short diameter of approximately 1.1 cm, with increased FDG uptake (SUVmax = 4.6).
Mild pleural thickening was observed bilaterally, but no pleural effusion or pneumothorax was present.
The cardiac silhouette appeared normal.
Calcification was observed in some arterial walls (including the coronary arteries).
The esophagus showed no dilation, no significant thickening or mass in the wall, and no increased FDG uptake.
The liver appeared normal in shape and size, with smooth borders and no widening of the hepatic fissure.
No abnormal density shadows were observed in the liver parenchyma, and 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 appeared normal in shape and size, with a slightly roughened wall and patchy high-density shadows within the gallbladder; FDG uptake was normal.
The pancreas appeared normal in shape and parenchyma, with no significant abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no significant abnormal FDG uptake.
Spleen morphology and size normal, density and FDG uptake normal.
Kidneys morphology and size normal, no obvious abnormal density shadows seen in the renal parenchyma, FDG uptake normal.
No widening of the renal pelvis, calyces, or ureters, no positive stones seen within.
Adrenal glands slightly thickened bilaterally, FDG uptake normal.
Stomach poorly distended, FDG uptake normal.
Intestinal preparation poor, no obvious masses seen in the intestinal wall, FDG uptake normal.
Prostate morphology and size normal, transverse diameter approximately 4.3 cm, calcifications seen in the parenchyma, FDG uptake normal.
Bladder poorly distended, no obvious positive stones seen within.
No enlarged lymph nodes seen in the abdominal cavity, pelvis, or retroperitoneal region, FDG uptake normal.
No obvious fluid accumulation in the abdomen or pelvis.
Slight anterior displacement of the L4 vertebral body.
Patchy hazy shadows were seen at the lower margin of the L1 vertebral body, with osteophyte formation at the margins of some vertebral bodies, and L5/S1 intervertebral disc bulging.

Impression

1. a. Solid nodule in the right middle lobe with increased FDG metabolism, highly suggestive of peripheral lung cancer; please confirm the diagnosis with pathological examination. Possible metastasis to the right hilar and mediastinal lymph nodes. b. Large patchy high-density shadow in the right lower lobe with increased FDG metabolism, suggestive of infectious lesions; CT follow-up after regular anti-infective treatment is recommended to rule out other complications. c. Old pulmonary tuberculosis in both lungs. Chronic inflammatory nodules in both lungs. Pulmonary fibrosis and emphysema in both lungs. Mild pleural thickening bilaterally. Partial arteriosclerosis (including coronary arteries).

2. Gallstones, chronic cholecystitis. Bilateral adrenal hyperplasia. Prostatic calcification.

3. Spinal degeneration. L4 vertebral instability. L1 vertebral endplate inflammation. L5/S1 intervertebral disc bulge.

4. Sellar region mass with increased FDG metabolism; enhanced MRI is recommended for further examination.

5. Bilateral deep lacunar insufficiency lesions in the brain. Right maxillary 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.
