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: Brain morphology and structure were normal, with patchy, slightly low-density lesions in the left frontal lobe; FDG uptake was not significantly abnormal.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical and without significant abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; FDG uptake was not abnormal; the pharyngeal recesses were symmetrical; there was no stenosis of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the parapharyngeal spaces were clear bilaterally, and FDG uptake was not abnormal.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
The thyroid gland is normal in shape and size, with uneven density.
Focal FDG uptake is observed in the left lobe, with SUVmax = 6.4.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
A ground-glass nodule in the apical-posterior segment of the left upper lobe, with clear borders and seemingly shallow lobulation at the edges, measures approximately 1.3*1.1cm, with a maximum CT value of -484HU.
Vacuoles are seen within the nodule.
FDG uptake is normal.
A ground-glass nodule in the superior lingular segment of the left upper lobe, with a long diameter of approximately 0.4cm and a maximum CT value of -581HU, shows normal FDG uptake.
Solid nodules in the inferior lingular segment of the left upper lobe and the anteromedial basal segment of the left lower lobe, the largest being approximately 0.4cm in diameter, show no abnormal FDG uptake.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette appears normal, with the cardiac chamber density slightly lower than that of the myocardium.
Bilateral mammary glands are dense, and FDG metabolism is normal.
Small axillary lymph nodes are visible bilaterally, the largest with a short diameter of approximately 0.9 cm; FDG metabolism is normal.
The esophagus is not dilated, and the wall is not significantly thickened or swollen; FDG uptake is not increased.
The liver is normal in shape and size, with smooth borders, no widening of the hepatic fissure, and no obvious abnormal density shadows in the liver parenchyma on plain CT scan; 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; local FDG uptake is normal.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma; the main pancreatic duct is not widened; FDG uptake is normal.
Spleen morphology, size, and density were normal.
Patchy FDG uptake was observed in the spleen, SUVmax=6.2, with an uptake area of approximately 3.5*2.2*3.8cm; density was slightly decreased on the same CT slice.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
No widening of the renal pelvis, calyces, or ureters was observed, and FDG uptake was not significantly abnormal.
Bilateral adrenal glands showed no obvious abnormalities on contrast.
Stomach was poorly distended, with no obvious thickening of the gastric wall, and FDG uptake was not significantly abnormal.
Intestinal distending was poor, with no obvious thickening or mass in the intestinal wall; FDG uptake was physiological.
Uterus was normal in shape and size, with no abnormal density shadows.
Patchy FDG uptake was observed in the endometrial area, SUVmax=4.9.
A cystic lesion was observed in the left adnexa, approximately 2.0*1.9cm in size; FDG metabolism was not abnormal.
The bladder was poorly filled, but no obvious stones were observed.
No enlarged lymph nodes were seen in the abdominal cavity, pelvis, or retroperitoneal region.
A small amount of pelvic effusion was present.
The spinal alignment was normal, and whole-body bone mineral density and whole-body bone marrow FDG metabolism were normal.

Impression

1. a. Ground-glass nodule in the apical-posterior segment of the left upper lobe, FDG metabolism normal, likely early-stage lung cancer; please correlate with clinicopathology. b. Ground-glass nodule in the superior lingular segment of the left upper lobe, FDG metabolism normal, suggest inflammation or atypical adenomatous hyperplasia; annual HRCT follow-up recommended. c. Chronic inflammatory micronodule (solid) in the left lung. Mild anemia changes.

2. Patchy FDG elevation in the spleen, slightly decreased density on same-slice CT, space-occupying lesion to be ruled out; further enhanced MRI recommended.

3. Focal FDG elevation in the left lobe of the thyroid gland, suggestive of adenomatous nodule, malignancy to be ruled out; further ultrasound examination recommended.

4. Bilateral breast hyperplasia. Reactive hyperplasia of bilateral axillary lymph nodes.

5. Physiological uptake in the uterine cavity; cystic lesion in the left adnexa; follow-up ultrasound is recommended. Small amount of pelvic effusion.

6. Possible ischemic lesion in the left frontal lobe; follow-up MRI is recommended to rule out other possibilities.

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.
