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 scan showed: Brain morphology and structure were normal, with a few punctate low-density shadows in the deep brain regions; FDG uptake was not significantly abnormal.
The ventricles, sulci, fissures, and cisterns were widened; the ventricles were symmetrical bilaterally, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no significant abnormalities.
The left maxillary sinus mucosa was thickened, but the sinus wall was intact.
The nasopharyngeal wall was not thickened; FDG uptake was not abnormal.
The pharyngeal recesses were symmetrical bilaterally; there was no narrowing of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the bilateral parapharyngeal spaces were clear, and FDG uptake was not abnormal.
The palatine tonsils showed physiological uptake bilaterally.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
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.
Irregular soft tissue shadows with local bronchial obstruction were seen in the anterior segment of the right upper lobe and the posterior segment of the right lower lobe, measuring approximately 2.0*1.5cm and 2.9*1.8cm respectively, with increased FDG metabolism (SUVmax=10.4).
Postoperative left lung cancer surgery; no obvious abnormalities were seen in the surgical area.
Multiple linear shadows were seen in both lungs, more prominent in the right lower lobe.
Calcifications were found in the right hilum, right lower lobe, and right pleura.
No pleural thickening was seen bilaterally; no pleural effusion or pneumothorax was observed bilaterally.
An enlarged lymph node was seen in the right hilum, with a short diameter of approximately 0.8cm; FDG metabolism was increased (SUVmax=6.7).
Several small lymph nodes, approximately 0.5 cm in short diameter, were seen in the pretracheal space and main pulmonary artery window.
FDG metabolism was increased, with an SUVmax of 3.2.
Calcification was observed in some arterial walls (including the coronary arteries).
The cardiac silhouette appeared normal.
The esophagus showed no dilation, no significant thickening or mass in the wall, and no increased FDG uptake.
The liver's shape and size were normal, with smooth borders and no widening of the hepatic fissure.
Plain CT scan showed decreased liver parenchymal density (CT value approximately 43 HU), and no abnormal FDG uptake.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts.
The gallbladder's shape and size were normal, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no significant abnormal FDG uptake.
Spleen morphology, size, density, and FDG uptake were normal.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters were not widened, and FDG uptake was not significantly abnormal.
Bilateral adrenal glands showed no obvious abnormalities on contrast imaging.
Stomach distension was poor, with no obvious thickening of the stomach wall, and no obvious abnormalities in FDG uptake.
Intestinal distension was poor; a linear dense shadow was seen in the sigmoid colon, and continuous FDG metabolism was increased in the sigmoid colon and rectum, with SUVmax=3.6.
The prostate was normal in shape and size, with punctate calcifications inside, and no abnormal FDG metabolism was observed.
The bladder wall showed no abnormal thickening, and no obvious positive stones were seen inside.
No enlarged lymph nodes were seen in the abdominal and pelvic regions or retroperitoneal area.
No obvious effusion was seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with some vertebral body margin osteophytes, some lumbar intervertebral discs with pneumothorax, and L3/4 and L4/5 disc bulges.
Systemic bone FDG metabolism is normal.

Impression

1. a. Space-occupying lesions in the anterior segment of the right upper lobe and the posterior segment of the right lower lobe, accompanied by increased FDG metabolism, consistent with lung cancer. Right hilar lymph node metastasis. Mediastinal lymph node metastasis to be ruled out, follow-up is required. b. Postoperative changes after left lung cancer surgery. Multiple chronic inflammations and sequelae in both lungs. Calcifications in the right hilum, right lower lobe, and right pleura. Calcification of some arterial walls (including coronary arteries).

2. Mild fatty liver. Prostatic calcification. Schistosomiasis intestinal disease.

3. Continuous increased FDG metabolism in the sigmoid colon and rectum, suggesting possible inflammatory uptake; colonoscopy is recommended to rule out tumors.

4. Partial vertebral osteophyte formation. Partial lumbar disc pneumothorax, L3/4 and L4/5 disc bulges.

5. A few ischemic lesions in the deep brain. Age-related brain changes. Left 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.
