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 tomographic images showed: The brain morphology and structure were normal; no abnormal density shadows were seen in the brain parenchyma, and FDG uptake was normal.
No widening was observed in the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical, and no obvious abnormalities were observed.
No thickening was seen in the paranasal sinus mucosa, and the sinus walls were intact.
No thickening was seen in the nasopharyngeal wall, and FDG uptake was normal.
The 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.
No abnormal FDG uptake was seen in the oropharynx and laryngopharynx.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
Increased density was observed in the left mastoid airway, but no abnormal FDG uptake was observed.
The thyroid gland is normal in shape and size, with uniform density, and no abnormalities in FDG uptake.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, or submental region; FDG metabolism was normal.
An irregular mass with indistinct borders and irregular edges was observed in the right upper lobe near the hilum, with increased FDG uptake.
The mass measures approximately 3.2 3.0 cm, with an SUVmax of 19.9.
The corresponding bronchus is compressed and narrowed, and forked soft tissue shadows are visible around it.
Multiple nodules were observed in both lungs, most notably in the left upper lobe, with the largest nodule having a long diameter of approximately 1.2 cm.
Multiple calcifications and linear shadows were also observed.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
Multiple lymph nodes were observed in the mediastinum, with the largest nodule having a short diameter of approximately 0.5 cm.
Some of these lymph nodes contained calcifications, and some showed increased FDG uptake, with an SUVmax of 3.8.
The cardiac silhouette was normal.
Both breasts are relatively dense, and FDG metabolism is normal.
The liver is normal in shape and size, with smooth liver margins and no widening of the hepatic fissure.
CT scan shows no obvious abnormal density shadows in the liver parenchyma, and FDG uptake is normal.
The main portal vein is not significantly widened, and there is no dilation of intrahepatic or extrahepatic bile ducts.
The gallbladder is normal in shape and size, with no thickening of the gallbladder wall, and no abnormal local FDG uptake.
The pancreas is 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 is normal in shape, size, density, and FDG uptake.
A type of small splenic nodule is visible around the spleen, but no abnormal FDG uptake is observed.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows seen 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 imaging.
The esophagus is not dilated, and the esophageal wall is not significantly thickened or swollen; FDG uptake is not increased.
The stomach is poorly distended, and the stomach wall is not significantly thickened; FDG uptake is not significantly abnormal.
The intestines are poorly distended, and the intestinal wall is not significantly thickened or swollen; FDG uptake is physiological.
The uterus is full in shape with slightly irregular edges; FDG uptake is not abnormally increased.
No abnormal FDG metabolism is seen in the bilateral adnexa.
The bladder is generally full, and no obvious positive stones are seen within it.
No enlarged lymph nodes are seen in the abdomen, pelvis, or retroperitoneal region; FDG metabolism is not abnormal.
No obvious effusion is seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with some vertebral body margin osteophytes, and L3/4 and L4/5 intervertebral disc bulges.
FDG uptake is normal.
Bilateral sacroiliac joints show increased density, but the joint spaces are present; FDG metabolism is normal.
Systemic bone marrow FDG metabolism is normal.

Impression

1. a. A mass near the hilum in the right upper lobe of the lung, with increased FDG metabolism, consistent with lung cancer and surrounding obstructive changes. b. Multiple chronic inflammatory nodules in both lungs, possibly old tuberculosis in the left upper lobe. Reactive hyperplasia of mediastinal lymph nodes; follow-up is recommended.

2. Accessory spleen. Uterine fibroids.

3. Spinal osteophyte formation. L3/4 and L4/5 intervertebral disc bulge. Bilateral sacroiliac joint condensation osteitis.

4. No obvious abnormalities were seen on cranial imaging; MRI is recommended. Left mastoiditis.

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.
