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 scan revealed: multiple irregular low-density edema in the brain, with multiple irregular low-density nodules and masses within the brain parenchyma, the largest being approximately 3.2 2.8 cm in the left temporal lobe, showing increased FDG metabolism (SUVmax = 6.2).
Bilateral ventricular compression was observed, with mild rightward deviation of the midline structures.
The eyes were symmetrical and showed no obvious abnormalities.
A cystic lesion was observed in the right maxillary sinus with an intact sinus wall.
A cystic lesion measuring approximately 1.9 1.0 cm was observed in the midline of the maxilla, with normal FDG metabolism.
The nasopharyngeal wall showed no thickening, 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 normal FDG uptake.
Bilateral palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx were normal.
The thyroid gland was normal in shape and size, with slightly heterogeneous density; FDG uptake was normal.
No enlarged lymph nodes were seen in bilateral deep cervical spaces or submandibular regions.
Increased translucency of both lungs, accompanied by multiple air-filled cavities; an irregular mass measuring approximately 4.33.42.9cm was seen in the posterior segment of the right upper lobe, with lobulated and spiculated margins, and increased FDG metabolism (SUVmax=10.6); several solid nodules, approximately 0.2-0.5cm in long diameter, with clear borders, were seen in the right middle lobe and interlobar pleura, with some showing slight FDG uptake; several ground-glass nodules, approximately -623 HU on CT, approximately 0.2-0.3cm in long diameter, with relatively clear borders, and no abnormal FDG metabolism were seen in the upper lobes of both lungs.
A few speckled, linear lesions and calcifications were observed in both lungs, with no abnormalities in FDG metabolism.
There was no pleural effusion or pneumothorax bilaterally.
Several small lymph nodes were observed in the bilateral hilum, pretracheal space, para-aortic arch, aortopulmonary window, and below the carina, the largest being approximately 0.4 cm in short diameter; FDG metabolism was normal.
The cardiac silhouette was normal.
Some arterial walls showed calcification.
The esophagus was not dilated, and the wall was not significantly thickened or swollen; FDG uptake was not increased.
The liver's shape and size were normal, with smooth borders and no widening of the hepatic fissure; multiple cystic lesions were observed within the liver, the largest approximately 1.1 cm in long diameter, with absent FDG uptake.
The main portal vein was not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder's shape and size were normal, the gallbladder wall was not thickened, and local FDG uptake was normal.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct is not widened, and FDG uptake is not significantly abnormal.
The spleen is normal in shape, size, density, and FDG uptake.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal glands show no obvious abnormalities on contrast.
The stomach is poorly distended, with no obvious thickening of the stomach wall, and FDG uptake is not significantly abnormal.
The intestines are poorly distended, with no obvious thickening or mass in the intestinal wall, and FDG uptake is physiological.
The prostate is normal in shape and size, with uniform density, and no abnormal FDG metabolism is observed.
The bladder is generally full, with no obvious positive stones.
No enlarged lymph nodes are seen in the abdominal cavity, pelvis, or retroperitoneal region.
No obvious fluid accumulation was observed in the abdomen or pelvis.
The spinal alignment was normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulges.
Increased FDG metabolism was observed around both shoulder joints, with SUVmax = 3.2.
Localized bone destruction was observed in the left 9th posterior rib, with increased FDG uptake, SUVmax = 3.7.
No abnormalities were found in systemic bone marrow FDG metabolism.

Impression

1. a. Right upper lobe posterior segment mass, elevated FDG metabolism, suggestive of lung cancer. b. Multiple intracranial metastases. Metastasis to the left 9th posterior rib. c. Ground-glass nodules in both upper lobes, normal FDG metabolism, suggestive of inflammatory nodules or atypical adenomatous hyperplasia; annual HRCT follow-up recommended. d. Possible chronic inflammatory nodules in the right middle lobe and interlobar pleura, metastasis to be ruled out; follow-up recommended. Bilateral emphysema. A few chronic inflammations and old lesions in both lungs. e. Reactive hyperplasia of bilateral hilar and mediastinal lymph nodes. Calcification of some arterial walls.

2. Liver cyst.

3. Degenerative changes in the spine. L4/5, L5/S1 intervertebral disc bulge. Bilateral frozen shoulder.

4. Right maxillary sinus submucosal cyst. Cyst in the midline of the maxilla.

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.
