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: Post-operative left brain lesion: bone interruption in the surgical area.
Several slightly high-density nodules were seen in the left temporoparietal-occipital lobe, the largest measuring approximately 2.4*1.5cm in the occipital lobe, with increased FDG uptake (SUVmax=4.3), surrounded by patchy low-density shadows.
No widening was observed in the ventricles, sulci, fissures, or cisterns; local density and FDG uptake were normal; midline structure shift was normal.
Bilateral ocular morphology and contours were normal; retrobulbar structures were clear; bilateral optic nerves were symmetrical; FDG uptake was normal.
No thickening of the paranasal sinus mucosa was observed; sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; FDG uptake was normal; bilateral pharyngeal recesses were symmetrical; Eustachian tube openings were not narrowed; infratemporal and pterygopalatine fossae were normal; bilateral parapharyngeal spaces were clear; FDG uptake was normal.
Bilateral palatine tonsils were full; FDG uptake was physiological.
The morphology and structure of the laryngopharynx are normal.
No abnormal visualization of the bilateral salivary glands is observed.
The thyroid gland is normal in shape and size, with uniform density, and FDG uptake is normal.
No significantly enlarged lymph nodes are seen in the bilateral deep cervical spaces, submandibular region, and submental region, and FDG uptake is normal.
A soft tissue nodule measuring approximately 2.2*1.6cm is seen in the posterior segment of the left upper lobe, with lobulated and spiculated margins, containing small vacuoles, and adjacent pleural thickening.
FDG uptake is increased, SUVmax=1.9.
A soft tissue mass measuring approximately 4.1*2.3cm is seen near the hilum of the left upper lobe, with rough margins, local bronchial truncation, and increased FDG uptake, SUVmax=5.5.
Scattered punctate and linear shadows are seen in both lungs, and air-filled cavities are seen in the subpleural regions of both lungs.
No significantly enlarged lymph nodes are seen in the mediastinum, and FDG uptake is not significantly increased.
There is no pleural effusion or pneumothorax bilaterally.
The cardiac silhouette is normal.
The esophagus showed no dilation, thickening or masses in the esophageal wall, and no increased FDG uptake.
The liver was normal in shape and size, with smooth borders and no widening of the hepatic fissures.
No abnormal density shadows were observed in the liver parenchyma, and FDG uptake was normal.
The main portal vein was normal in size and shape, with no thickening of the gallbladder wall, no positive stones or obvious masses, and no abnormal FDG uptake.
The pancreas was normal in shape and size, with no abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no abnormal FDG uptake.
The spleen was normal in shape and size, with no abnormal density or FDG uptake.
Both kidneys were normal in shape and size, with no abnormal density shadows in the renal parenchyma, and no abnormal FDG uptake.
The renal pelvis, calyces, and ureters were normal in size and shape, with no positive stones.
The adrenal glands were normal in shape and density, and FDG uptake was normal.
Gastric distension was poor, but FDG uptake was not significantly abnormal.
Bowel preparation was poor, with no obvious masses in the intestinal wall, and FDG uptake was physiological.
The prostate gland was normal in shape and size, with a transverse diameter of approximately 4.1 cm, and no obvious abnormal density shadows were observed in the parenchyma; FDG uptake was not significantly increased.
Bladder distension was poor, but no obvious positive stones were observed.
No enlarged lymph nodes were observed in the abdominal cavity, pelvis, or retroperitoneal region, and FDG uptake was normal.
No obvious fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment was normal, with mild osteophyte formation at the margins of some vertebral bodies and L4/5 intervertebral disc bulging.
FDG uptake in all muscles was increased, with SUVmax = 5.1.

Impression

1. Postoperative changes following a left brain lesion; a slightly high-density nodule in the left temporoparietal-occipital lobe with increased FDG metabolism, suggestive of a metastatic tumor.

2. a. Lung cancer in the apical-posterior segment of the left upper lobe; lung cancer or metastatic lymph nodes in the left hilar region. b. Chronic inflammation and sequelae in both lungs. Paraseptal emphysema in both lungs.

3. Mild osteophyte formation in some vertebral bodies. L4/5 intervertebral disc bulge.

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.
