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:Normal brain morphology and structure, with punctate low-density lesions in the deep bilateral cerebral regions; no significant abnormalities in FDG metabolism.
Slight widening of the ventricles, sulci, fissures, and cisterns; symmetrical bilateral ventricles; no midline shift.
Normal bilateral eyeball morphology and contour; clear retrobulbar structures; symmetrical bilateral optic nerves; no abnormal FDG metabolism.
Slight thickening of the mucosa in the left maxillary sinus; intact sinus wall; absent FDG metabolism.
No thickening of the nasopharyngeal wall; no stenosis of the bilateral pharyngeal recesses and Eustachian tube openings; normal structures of the infratemporal fossa and pterygopalatine fossa; clear bilateral parapharyngeal spaces; no abnormal FDG metabolism.
Physiological FDG metabolism in the oropharynx and laryngopharynx.
No abnormal contrast enhancement of the bilateral parotid and submandibular glands.
Post-thyroid nodule removal surgery, the thyroid gland showed irregular shape and uneven density, with diffusely increased FDG metabolism (SUVmax = 6.2).
Small lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region, the largest measuring approximately 0.6 cm in short diameter; FDG metabolism was normal.
An irregular soft tissue density mass was observed in the right upper lobe near the hilar bronchial opening, with indistinct borders, measuring approximately 5.4 x 4.9 cm in cross-section.
FDG metabolism was unevenly increased (SUVmax = 12.6), with distal lung atelectasis and unclear demarcation from the right pulmonary artery.
Scattered ground-glass opacities were observed in the right lung, with some areas showing increased FDG metabolism (SUVmax = 8.2).
A solid nodule with a long diameter of approximately 0.3 cm was observed in the subpleural region of the apical posterior segment of the right upper lobe; the nodule was regular in shape, with clear borders, and FDG uptake was normal.
A few linear and flocculent density shadows were observed in both lungs, with no abnormalities in FDG metabolism.
The pleura was slightly thickened bilaterally, but there was no pleural effusion or pneumothorax.
Lymph nodes were visualized in the right hilum and mediastinum, pretracheal and post-tracheal lymph nodes, the largest with a short diameter of approximately 2.5 cm, showing unevenly increased FDG metabolism in some areas (SUVmax = 12.2).
The cardiac silhouette was normal, with slight pericardial thickening.
No obvious masses or nodules were seen in either breast, with no significant abnormalities in FDG metabolism.
The liver's shape and size were normal, with smooth borders and no widening of the hepatic fissure.
Plain CT scan showed no obvious abnormal density shadows in the liver parenchyma, and no abnormalities in FDG metabolism.
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, with a nodular shadow resembling a 0.7 cm long diameter at the gallbladder fundus; local FDG metabolism 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 metabolism is normal.
The spleen is normal in shape, size, density, and FDG metabolism.
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 metabolism is normal.
Bilateral adrenal glands show no obvious abnormalities on contrast.
The esophagus is not dilated, and the wall is not significantly thickened or swollen; FDG metabolism is not increased.
The stomach is poorly distended, but the wall is not significantly thickened, and FDG metabolism is normal.
The intestines are poorly distended, but the wall is not significantly thickened or swollen; FDG metabolism is physiological.
An air-filled cavity is seen in the descending duodenum; FDG metabolism is normal.
A mass of isodense density, approximately 5.0*6.0cm in cross-section, is seen at the fundus of the uterus, containing near-calcified foci.
FDG metabolism is normal.
No obvious abnormalities are seen in the bilateral adnexa.
The bladder is poorly filled, but no obvious positive stones are seen.
No enlarged lymph nodes are seen in the abdomen, pelvis, or retroperitoneum.
No obvious fluid accumulation is seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with some vertebral body margin osteophytes.
L4/5 and L5/S1 intervertebral disc bulges, but FDG metabolism is normal.

Impression

1. a. A mass near the bronchial opening in the right upper lobe, with unevenly increased FDG metabolism, suggestive of central lung cancer with right upper lobe atelectasis, likely involving the right pulmonary artery. Further clinical and pathological examination is recommended. Mediastinal and right hilar lymph node metastases, some with necrosis. b. Scattered ground-glass opacities in the right lung, some with increased FDG metabolism, suggestive of inflammation. Follow-up CT scan recommended. c. A small, solid, chronic inflammatory nodule in the subpleural region of the apical-posterior segment of the right upper lobe. Further follow-up CT scan recommended. A few post-inflammatory lesions in both lungs. Mild pleural thickening bilaterally. Slight pericardial thickening.

2. Postoperative changes in thyroid nodules: irregular thyroid morphology, uneven density with diffusely increased FDG metabolism, suggestive of thyroiditis or hyperthyroidism. Ultrasound and thyroid function tests recommended.

3. Possible gallbladder polyp; ultrasound follow-up recommended. Uterine fibroids with calcification. Duodenal diverticulum.

4. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulges.

5. Mild age-related brain changes, deep lacunar infarcts in the brain; MRI is recommended. Minor inflammation of the left maxillary sinus. Reactive hyperplasia of bilateral deep cervical interspace, submandibular, and submental lymph nodes.

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.
