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, and resting, a whole-body PET/CT scan was performed.
The whole-body tomographic images 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 bilateral eyeballs had normal morphology and outline, with clear retrobulbar structures and no abnormal FDG uptake.
No significant thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No significant thickening of the soft tissue on both sides of the nasopharyngeal wall was observed, the bilateral pharyngeal recesses were symmetrical, and no abnormal FDG uptake was observed.
FDG uptake in the bilateral palatine tonsils was physiological.
The laryngopharynx had normal morphology and structure, and the parapharyngeal space was clear.
The bilateral parotid and submandibular glands had normal size, shape, and density, and FDG uptake was physiological.
The thyroid gland is normal in shape and size, with no obvious abnormal density shadows, and FDG uptake is normal.
No obviously enlarged lymph nodes are seen in the bilateral deep cervical spaces, submandibular region, and submental region, and FDG uptake is normal.
An irregular soft tissue mass is seen in the right lower lobe, with relatively clear borders, heterogeneous density, and patchy low-density lesions.
FDG uptake is increased (SUVmax = 16.3), with an uptake range of approximately 4.6 4.0 4.4 cm.
Spiculated shadows are seen at the edges.
Adjacent bronchi are narrowed or obstructed, and the distal lung parenchyma is partially atelectasis.
Patchy, linear, and punctate calcifications are seen in the left upper lobe and posterior segment of the lower lobe, predominantly in the left upper lobe, accompanied by increased FDG uptake (SUVmax = 1.3).
The pleura is slightly thickened bilaterally, but no obvious pleural effusion is seen bilaterally.
No obvious enlarged lymph nodes were observed in the bilateral hilum and mediastinum, and FDG uptake was not significantly increased.
The heart size was normal.
Calcification was observed in the walls of the aorta and its branches (including the coronary arteries).
The esophagus was not dilated, but the lower segment wall was slightly thickened, with increased FDG uptake (SUVmax = 4.3).
The stomach was adequately filled, with slight thickening of the gastric wall in some areas, and increased FDG uptake (SUVmax = 2.5).
Intestinal filling was unsatisfactory; no local masses were observed, and some intestinal segments showed physiological FDG uptake.
The esophageal hiatus was slightly widened, and a significant amount of fat density was observed in the posterior mediastinum, but FDG uptake was normal.
The liver morphology and size were normal, with smooth borders and no widening of the hepatic fissure.
A cystic low-density lesion approximately 1.3 cm in diameter was observed in the left inner lobe of the liver, with clear borders and absent FDG uptake.
No dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder is normal in shape and size, the gallbladder wall is not thickened, no positive stones or obvious masses are seen, and FDG uptake in the gallbladder fossa is normal.
The peripancreatic spaces are clear, no obvious abnormal density shadows are seen in the parenchyma, the pancreatic duct is not widened, and FDG uptake is normal.
The spleen is basically normal in shape and size, and its density and FDG uptake are normal.
The bilateral adrenal glands are normal in shape, size, and density, and local FDG uptake is normal.
The bilateral kidneys are normal in shape and size, no obvious abnormal density shadows are seen in the renal parenchyma, and FDG uptake is normal.
No widening of the bilateral renal pelvis, calyces, and ureters is seen, and no positive stones are seen locally.
The bladder is well filled, the bladder wall is not locally thickened, no positive stones are seen in the lumen, and FDG uptake is normal.
The prostate gland appears normal in shape and size, but contains punctate calcifications.
No focal abnormal increases in FDG uptake were observed.
No enlarged lymph nodes were observed in the retroperitoneal region, and FDG uptake was normal.
No significant effusion was observed in the abdominal or pelvic cavities.
The spinal alignment is unstable, with osteophyte formation at the margins of some vertebral bodies and facet joints.
The L1 and L2 vertebral bodies are slightly displaced posteriorly, and the L5 vertebral body is slightly displaced anteriorly with bilateral pars interarticularis fractures.
No abnormal FDG uptake was observed.
Increased FDG uptake was observed in the soft tissues around the right shoulder joint, with SUVmax = 3.2.

Impression

1. a. Space-occupying lesion in the lower lobe of the right lung, with significantly increased FDG metabolism, consistent with lung cancer with obstructive atelectasis based on pathology. b. Old fibrosis and calcifications in the upper and posterior segments of the lower lobe of the left lung. Partial arteriosclerosis (including coronary arteries).

2. Chronic inflammatory changes in the lower esophagus and stomach; gastroscopy follow-up may be necessary. Hiatal hernia.

3. Liver cyst. Prostatic calcifications.

4. Degenerative changes in the spine, instability of the L1, L2, and L5 vertebral bodies with bilateral pars interarticularis fractures at L5. Right-sided frozen shoulder.

5. No obvious abnormalities were found on cranial scintigraphy.

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.
