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: A soft tissue mass, approximately 7.2 6.2 cm, was visible in the right frontal lobe, compressing the adjacent ventricle and partially extending across the midline.
FDG uptake was absent, and cerebral edema was observed around the mass.
The adjacent skull bones were slightly thinned.
Midline structures were deviated to the left.
Both eyes were symmetrical, with no obvious abnormalities.
The mucosa of the right ethmoid sinus, both maxillary sinuses, and both sphenoid 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.
The morphology and structure of the laryngopharynx were normal.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The thyroid gland is normal in shape and size, with uniform density, and FDG uptake is normal.
No significantly enlarged lymph nodes were seen in the bilateral deep cervical spaces, submandibular region, and submental region, and FDG metabolism was normal.
Postoperatively, high-density suture shadows were seen in the surgical area, but FDG uptake was normal; multiple solid nodules were seen in both lungs, with relatively clear borders, the largest being approximately 0.3 cm in length, and scattered linear shadows were seen in both lungs, but FDG uptake was normal.
The pleura is slightly thickened bilaterally, but there is no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette is full.
Partial calcification is present in the walls of the aorta and coronary arteries.
The liver is normal in shape and size, with smooth liver margins and no widening of the hepatic fissure.
A small cystic lesion, approximately 0.6 cm in length, is visible in the right posterior lobe of the liver, but FDG uptake is normal.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder was normal in shape and size, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormal FDG uptake.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
The left kidney showed localized thinning of the parenchyma with a slightly concave outer margin, dense shadows in the left renal pelvis and calyces, and mild dilation of the left ureter; no abnormal FDG uptake was observed.
The right kidney was normal in shape and size, with no obvious abnormal density shadows in the parenchyma, no widening of the renal pelvis, calyces, or ureter, and no obvious abnormal FDG uptake.
Bilateral adrenal gland contrast was normal.
The esophagus was not dilated, with no obvious thickening or mass in the esophageal wall, and no increased FDG uptake.
The stomach is not fully full, but the stomach wall is not significantly thickened, and FDG uptake is normal.
The intestines are not fully full, but the intestinal wall is not significantly thickened or lumpy, and FDG uptake is normal.
The prostate is of normal size and uniform density, and FDG uptake is normal.
The bladder is generally full, and no obvious positive stones are seen.
No enlarged lymph nodes are seen in the abdomen, pelvis, or retroperitoneal region, and FDG metabolism is normal.
After repair of the right inguinal hernia, no abnormal density shadows are seen in the surgical area, and FDG uptake is normal.
A small amount of fluid density shadow is seen in the tunica vaginalis of the right testis.
The spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies, calcification of the nuchal ligament, slight anterior displacement of the L4 vertebral body, and bulging of the L3/4 and L4/5 intervertebral discs, but FDG uptake is normal.
FDG uptake of the right shoulder joint capsule is increased, with SUVmax=5.2.

Impression

1. a. Postoperative right lung cancer surgery, no obvious signs of tumor recurrence in the surgical area. b. Right frontal lobe mass, FDG uptake deficiency, suggestive of neoplastic lesion, metastasis is the primary consideration, glioma to be ruled out, further examination with contrast-enhanced MRI recommended.

2. Multiple chronic inflammatory micronodules in both lungs, a few post-inflammatory lesions in both lungs. Slight thickening of the pleura bilaterally. Full cardiac silhouette. Partial calcification of the aorta and coronary artery walls.

3. Small cyst in the right posterior lobe of the liver. Left kidney stone, thinning of the left renal parenchyma, mild dilation of the left ureter. Postoperative changes after right inguinal hernia repair. Small amount of hydrocele in the right testis.

4. Spinal degenerative changes. Mild anterior slippage of the L4 vertebral body. L3/4 and L4/5 intervertebral disc bulge. Right frozen shoulder.

5. Inflammation of the right ethmoid sinus, bilateral maxillary sinuses, and bilateral sphenoid 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.
