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, with no abnormal density shadows in the brain parenchyma, and no significant abnormalities in FDG uptake.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical, with no significant abnormalities.
The bilateral ethmoid sinus mucosa was slightly thickened, but the paranasal sinus mucosa was not thickened, and the sinus walls were intact.
The nasal septum was deviated, but the nasopharyngeal wall was not thickened, and FDG uptake was normal.
The bilateral 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.
The bilateral palatine tonsils showed physiological uptake.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The laryngopharynx morphology and structure were normal.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
An irregular nodular lesion with indistinct borders, measuring approximately 2.2*1.4*1.6cm, was observed in the posterior segment of the right lower lobe.
FDG uptake was increased, with SUVmax=4.5.
Stenosis of the bronchus in the adjacent posterior segment of the right lower lobe was observed, and a blurred patchy shadow was seen distal to the lesion.
Multiple solid nodules were observed in the remaining lungs, the largest being approximately 0.4cm in diameter; FDG uptake was normal.
A few air-filled cavities and scattered linear lesions were observed in both lungs; FDG uptake was normal.
A small amount of pleural effusion with pleural thickening was observed on the right side.
Multiple enlarged lymph nodes were observed in the right hilum, pretracheal space, aortic window, and below the carina, the largest measuring approximately 2.4 cm in short diameter, with increased FDG uptake (SUVmax = 6.8).
The right hilar lymph nodes invaded the basal segment of the right lower lobe bronchus.
Left hilar lymph nodes were also observed, the largest measuring approximately 1.0 cm in short diameter, with increased FDG uptake (SUVmax = 3.0).
The cardiac silhouette was normal.
Partial arteriosclerosis was present.
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 borders and no widening of the hepatic fissure.
Several cystic lesions were observed in the left lobe, the largest located in the left lateral lobe, measuring approximately 1.4 cm in long diameter, with no abnormal FDG uptake.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
Gallbladder: No abnormalities in shape or size, no thickening of the gallbladder wall, and no abnormalities in local FDG uptake.
Pancreas: Normal shape, no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormalities in FDG uptake.
Spleen: No abnormalities in shape, size, density, or FDG uptake.
Both kidneys: Normal shape and size, high-density shadows in the renal parenchyma, a cystic lesion at the upper pole of the right kidney (approximately 0.9 cm in diameter), no abnormalities in FDG metabolism, no widening of the renal pelvis, calyces, or ureter, and no obvious abnormalities in FDG uptake.
No obvious abnormalities were observed in bilateral adrenal gland imaging.
Stomach: Poor distension, with a significant amount of residual contents, no obvious thickening of the stomach wall, and no obvious abnormalities in FDG uptake.
Intestinal: Poor distension, no obvious thickening or mass in the intestinal wall, and FDG uptake is physiological.
The prostate is of normal size, with punctate dense shadows visible inside; FDG uptake is not abnormally increased.
The bladder is adequately full, with increased density shadows visible inside.
No enlarged lymph nodes were seen in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No significant fluid accumulation was seen in the abdominal or pelvic cavities.
Overall muscle uptake is high; the spinal alignment is normal; bilateral pars interarticularis ischemia at L5, with osteophyte formation at some vertebral margins; L3/4, L4/5, and L5/S1 intervertebral disc bulges.
Systemic bone marrow FDG metabolism is normal.

Impression

1. a. A mass in the posterior segment of the right lower lobe with increased FDG metabolism, consistent with lung cancer with obstructive inflammation. Multiple lymph node metastases in the right hilum and mediastinum. Reactive hyperplasia of the left hilar lymph nodes. b. Chronic inflammatory micronodules in the remaining two lungs are likely; follow-up CT is recommended. Mild emphysema in both lungs. A few post-inflammatory lesions in both lungs. Small amount of pleural effusion with pleural thickening on the right side. Partial arteriosclerosis.

2. Cyst in the left lobe of the liver. Cyst in the right kidney. Residual contrast agent in the urinary tract. Calcifications in the prostate.

3. Bilateral isthmic discontinuity at L5. Degenerative changes in the spine, bulging of the L3/4, L4/5, and L5/S1 intervertebral discs.

4. No obvious abnormalities were found on cranial scintigraphy. Chronic inflammation of both ethmoid sinuses.

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.
