Whole-body 18F-FDG PET/CT scan in a patient with Breast 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: The brain morphology and structure were normal; no abnormal density shadows were seen in the brain parenchyma, and FDG uptake was not significantly abnormal.
The ventricles, sulci, fissures, and cisterns were not widened; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical, and no significant abnormalities were observed.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasopharyngeal wall showed no thickening, and FDG uptake was not abnormal.
The pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the parapharyngeal spaces were clear with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
Thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
Lung markings are clear bilaterally; calcification is present in the lateral segment of the right middle lobe; FDG uptake is normal.
No pleural thickening was observed bilaterally; no pleural effusion or pneumothorax was present bilaterally.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette is normal; cardiac chamber density is slightly lower than myocardial density.
Both breasts have dense glandular tissue; multiple nodules and patchy slightly high-density shadows are present in the central and lateral regions of the left breast, with indistinct borders; the most prominent areas are located in the central region, with increased FDG uptake (SUVmax = 8.2), and an uptake range of approximately 2.4*1.6cm.
A calcification lesion with a diameter of approximately 0.3cm was found in the upper inner quadrant of the left breast; no significant space-occupying lesion was seen in the right breast; FDG metabolism is normal.
Bilateral axillary lymph nodes were observed, the largest being approximately 0.6 cm in short diameter; FDG metabolism was normal.
The esophagus showed no dilation, no significant thickening or mass in the esophageal wall, and no increased FDG uptake.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
A cystic lesion, approximately 1.0 cm in diameter, was present in the right posterior lobe of the liver; FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape or size, with increased density within the gallbladder; the gallbladder wall was not thickened, and local FDG uptake was normal.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma; the main pancreatic duct was not widened, and FDG uptake was normal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
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 gland imaging shows no obvious abnormalities.
The stomach is adequately filled, with slight thickening of the cardia and antral walls.
FDG uptake is mildly increased, SUVmax=2.1.
The intestines are not sufficiently filled, with a considerable amount of gas and residual contents in the lumen.
No obvious space-occupying lesions are seen in the intestines, and the uptake is physiological.
A cystic-solid mass is present in the right adnexal region, with indistinct borders, and a maximum cross-sectional size of approximately 9.1*6.7*cm.
The solid portion shows uneven FDG uptake, SUVmax=13.4.
A solid nodule is present in the left adnexal region, approximately 2.41.8cm in size, with increased FDG metabolism, SUVmax=10.6.
Multiple nodules and patchy soft tissue density shadows were observed in the right subdiaphragmatic region, liver capsule, splenic hilum, splenic capsule, greater omentum, mesentery, and pelvic floor fascia, with increased FDG uptake (SUVmax = 14.2).
A small amount of fluid was present in the abdominopelvic cavity.
The uterus was compressed.
Bladder filling was inadequate, but no obvious positive stones were observed.
Spinal alignment was normal.
Whole-body bone density and whole-body bone marrow FDG metabolism were normal.

Impression

1. a. Multiple lesions in the left breast with increased FDG metabolism, consistent with breast cancer; reactive hyperplasia of bilateral axillary lymph nodes is possible, follow-up is recommended. b. Bilateral breast hyperplasia, calcification in the left breast, ultrasound follow-up is recommended.

2. Cystic-solid mass in the right adnexal region, with increased FDG metabolism in the solid portion; solid nodule in the left adnexal region with increased FDG metabolism, both considered malignant tumors, most likely ovarian origin, metastasis to be ruled out, please combine clinical and enhanced MRI analysis; extensive peritoneal seeding metastasis, small amount of effusion in the abdominopelvic cavity.

3. Calcification in the right middle lobe of the lung. Mild anemia changes.

4. Possible right lobe hepatic cyst. Gallbladder bile concentration. Intrauterine device insertion.

5. Possible chronic inflammatory changes in the cardia and antrum of the stomach, please combine endoscopic follow-up.

6. No obvious abnormalities were found on cranial scintigraphy.

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.
