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: The brain morphology and structure were normal; no abnormal density shadows were seen in the brain parenchyma, and FDG uptake was normal.
There was no widening of the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical and showed no obvious abnormalities.
The mucosa of the right frontal sinus, bilateral ethmoid sinuses, and bilateral maxillary sinuses was thickened, but the sinus walls were intact.
The nasopharyngeal wall was not thickened, and FDG uptake was normal.
The pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal fossa and pterygopalatine fossa structures were normal, and the bilateral parapharyngeal spaces were clear with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx were normal.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
Two nodules fused into a soft tissue mass were seen in the right hilum, causing local bronchial compression in the right upper lobe; the mass measures approximately 5.4*3.2cm, with increased FDG metabolism (SUVmax=7.4).
A solid nodule in the apical segment of the right upper lobe, approximately 0.7cm in long diameter, showed normal FDG uptake.
A small solid nodule in the anterior basal segment of the right lower lobe, with clear borders, approximately 0.3cm in long diameter, showed normal FDG uptake.
Multiple cystic lucent shadows were observed in the upper lobes of both lungs.
No pleural thickening was seen bilaterally; there was no pleural effusion or pneumothorax bilaterally.
Several lymph nodes were seen in the pretracheal, posterior vena cava, and aortopulmonary artery windows; the largest had a short diameter of approximately 0.6cm, with slightly increased FDG metabolism (SUVmax=1.6).
The cardiac silhouette appears normal.
The esophagus shows no dilation, thickening, or mass in the wall; FDG uptake is normal.
The liver's shape and size are normal; the liver margins are smooth; the hepatic fissure is not widened; no abnormal density shadows are seen in the liver parenchyma on plain CT scan; FDG uptake is normal.
The main portal vein shows no significant widening; no dilation is seen in the intrahepatic or extrahepatic bile ducts.
The gallbladder's shape and size are normal; the gallbladder wall is not thickened; two 0.5cm dense shadows are seen locally; FDG uptake is normal.
The pancreas is normal in shape; no abnormal density shadows are seen in the parenchyma; the main pancreatic duct is not widened; FDG uptake is normal.
The spleen's shape, size, density, and FDG uptake are normal.
Both kidneys are normal in shape and size; a 1.2cm dense shadow is seen in the right renal calyx, and a punctate dense shadow is seen in the left renal calyx.
No widening of the renal pelvis, calyces, or ureter was observed, and FDG uptake showed no significant abnormalities.
Bilateral adrenal gland imaging showed no significant abnormalities.
Gastric distension was poor, but the gastric wall showed no significant thickening, and FDG uptake showed no significant abnormalities.
Intestinal distension was poor, with continuous FDG metabolism increased in the descending colon and sigmoid colon (SUVmax = 5.3).
The prostate gland was of normal size and shape, with uniform density, and no abnormal FDG metabolism was observed.
Bladder distension was normal, and no obvious positive stones were observed.
No enlarged lymph nodes were observed in the abdominal cavity, pelvis, or retroperitoneal region.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral body margin osteophytes.
Systemic bone marrow FDG metabolism was normal.

Impression

1. a. A mass in the right hilum with increased FDG metabolism, highly suggestive of malignancy, but inflammatory granulomatous lesions need to be ruled out. Please correlate with clinicopathology. b. A solid nodule in the apical segment of the right upper lobe, with normal FDG uptake, suggestive of a chronic inflammatory nodule, metastasis needs to be ruled out. Please monitor with CT. Reactive hyperplasia of mediastinal lymph nodes is highly probable. c. A small chronic inflammatory nodule in the anterior basal segment of the right lower lobe. Emphysema in both upper lobes of the lungs.

2. Right frontal sinusitis, bilateral ethmoid sinusitis, and bilateral maxillary sinusitis. No obvious abnormalities were found on cranial scintigraphy.

3. Continuous increased FDG metabolism in the descending colon and sigmoid colon, highly suggestive of inflammatory uptake or polypoid lesions. Colonoscopy is recommended for clarification.

4. Gallstones. Right kidney stone, small kidney stone in the left kidney.

5. Osteophytes in some vertebrae.

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.
