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 images showed: Normal brain morphology and structure; no abnormal density shadows were seen in the brain parenchyma; no significant abnormalities were observed in FDG uptake.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical and showed no significant abnormalities.
Slight thickening of the right maxillary sinus mucosa was observed; the mucosa of the remaining paranasal sinuses was not thickened, and the sinus walls were intact.
The nasal septum was deviated; the nasopharyngeal wall was not thickened; the palatine tonsils were symmetrical, and FDG uptake was physiological.
The laryngopharynx was normal in morphology and structure.
The parotid and submandibular glands were normal in morphology and density, and FDG uptake was physiological.
The thyroid gland was normal in morphology and size, with uniform density; FDG uptake was normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, or submental region.
The lung markings were clear, and an air-filled cavity was observed in the apical segment of the right upper lobe.
A few linear lesions were observed in both lungs, with no abnormal FDG uptake.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal, with the cardiac chamber density slightly lower than that of the myocardium.
No esophageal dilation was observed, and no significant thickening or mass was seen in the esophageal wall; FDG uptake was not increased.
Multiple nodules and patchy soft tissue density shadows were observed in the left breast, with increased FDG uptake (SUVmax = 9.9), containing punctate dense shadows, measuring approximately 4.6*1.6*5.5cm.
Multiple enlarged lymph nodes were observed in the left axilla, left interpectoral space, and left supraclavicular fossa; the largest was located in the left axilla, with a short diameter of approximately 1.1cm, and showed increased FDG uptake (SUVmax = 6.2).
The right breast glandular tissue was slightly dense, with no abnormal density shadows observed, and FDG metabolism was normal.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissures.
Plain CT scan showed no obvious abnormal density shadows in the liver parenchyma, and FDG uptake was normal.
The main portal vein showed no obvious widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape and size, but the gallbladder wall was thickened, and local FDG uptake was normal.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma, and the main pancreatic duct was not widened; FDG uptake was normal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma, and no widening of the renal pelvis, calyces, or ureters; FDG uptake was normal.
Bilateral adrenal glands showed no obvious abnormalities on contrast.
The stomach was adequately filled, with no thickening of the stomach wall, and FDG uptake was normal.
The intestines were not sufficiently filled, with no local masses observed, and FDG uptake was normal.
The uterus is normal in shape and size, with an intrauterine device (IUD) inserted.
A low-density lesion is present on the cervix, approximately 1.4 cm in length, with no abnormal FDG uptake.
No obvious abnormalities are seen in the bilateral adnexa.
The bladder is poorly filled, with no obvious positive stones.
No enlarged lymph nodes are seen in the abdominal cavity, pelvis, or retroperitoneum.
No significant fluid accumulation is seen in the abdomen or pelvis.
Multiple osteolytic bone destructions with increased FDG uptake are observed in the bilateral scapulae, left sternum, left 8th posterior rib, left C3 vertebral body, right T12 vertebral body, right L3 transverse process, left sacrum, and right iliac bone, with SUVmax = 7.6.
The spinal alignment is normal, with an L4/5 intervertebral disc herniation and posterior calcification, but no abnormal FDG uptake is seen.

Impression

1. a. Left breast mass with elevated FDG metabolism, suggestive of breast cancer. b. Multiple lymph node metastases in the left axilla, left interpectoral space, and left supraclavicular fossa. c. Multiple bone metastases throughout the body (see description for details).

2. Right upper lobe containing an air sac. A few post-inflammatory remnants in both lungs. Mild anemia.

3. Chronic cholecystitis. Intrauterine device insertion, Nabothian cyst in the cervix.

4. L4/5 intervertebral disc herniation with posterior calcification.

5. Cranial scintigraphy showed no obvious abnormalities. Chronic inflammation of the right maxillary sinus.

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.
