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 in FDG uptake were observed.
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 showed no significant abnormalities.
Thickening of the mucosa was observed in the bilateral ethmoid sinuses and the left maxillary sinus; the mucosa of the remaining paranasal sinuses was not thickened, and the sinus walls were intact.
Slight thickening of the left nasopharyngeal wall and shallowing of the pharyngeal recess were observed; FDG uptake was increased (SUVmax = 4.6).
The palatine tonsils were symmetrical; FDG uptake was physiological.
The morphology and structure of the laryngopharynx were normal.
The bilateral parotid and submandibular glands had normal morphology and density; FDG uptake was physiological.
The thyroid gland showed uneven density; FDG uptake was increased (SUVmax = 5.1).
Several ground-glass nodules were observed in the upper lobes of both lungs and the posterior basal segment of the left lower lobe, predominantly subpleural.
The largest, located in the posterior segment of the left upper lobe, measures approximately 0.4 cm in diameter, with a maximum CT value of -227 HU.
FDG uptake was normal.
A small solid nodule was observed in the apical segment of the right upper lobe, the largest measuring approximately 0.3 cm in diameter.
FDG uptake was normal.
A few linear lesions were present in both lungs, with normal FDG uptake.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
Lymph nodes were visualized in the pretracheal vena cava, aortopulmonary window, para-aortic arch, and subcarinal region.
The largest had a short diameter of approximately 0.6 cm and increased FDG uptake (SUVmax = 2.6).
The cardiac silhouette was normal.
The esophagus was not dilated, and the esophageal wall showed no significant thickening or mass.
FDG uptake was normal.
Bilateral breast tissue is dense.
A soft tissue mass with indistinct borders, measuring approximately 5.0*3.3*4.5cm, is present in the upper inner quadrant of the left breast.
The density is heterogeneous, with increased FDG uptake (SUVmax = 16.9).
A small nodular foci of increased FDG metabolism, SUVmax = 4.1, with an uptake diameter of approximately 0.8cm, are also present in the lateral part of the left breast.
No abnormal density shadows or FDG metabolism are observed in the right breast.
Multiple enlarged lymph nodes are present in the left axilla, left pectoral intermuscular space, left supraclavicular fossa, left posterior cervical triangle, and left deep cervical space.
The largest, located in the left axilla, has a short diameter of approximately 2.3cm and shows increased FDG uptake (SUVmax = 18.6).
The liver's morphology and size are normal, with smooth borders and no widening of the hepatic fissure.
Low-density nodules are present in the right posterior lobe and left lateral lobe, the largest, located in the right posterior lobe, with a diameter of approximately 1.1cm and increased FDG uptake (SUVmax = 10.4).
The remaining liver tissue shows heterogeneous density, but no abnormal FDG uptake is observed.
The main portal vein was not significantly widened, and the intrahepatic and extrahepatic bile ducts were not dilated.
The gallbladder was small, with thickened walls, but local FDG uptake was normal.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormal FDG uptake.
The spleen was normal in shape, size, density, and FDG uptake.
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, and no obvious abnormal FDG uptake.
Bilateral adrenal glands showed no obvious abnormalities on contrast.
The stomach was adequately filled, with slight thickening of the gastric wall in some areas, and increased FDG uptake (SUVmax = 4.1).
The intestines were not sufficiently filled, with no local masses, but continuous increased FDG uptake in the descending colon and sigmoid colon (SUVmax = 6.7).
The uterine margins were not smooth, with several soft tissue density bulges visible on the anterior wall, but no abnormal FDG uptake was observed; an intrauterine device was inserted, and no obvious abnormalities were seen in the bilateral adnexa.
The bladder is poorly filled, but no obvious stones are visible.
No enlarged lymph nodes are seen in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No significant fluid accumulation is seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with L4/5 intervertebral disc bulging, but no abnormal uptake is observed on FDG.
FDG uptake of the entire skeleton is normal.
Subcutaneous calcification is present in the left buttock.

Impression

1. a. A mass in the upper inner quadrant of the left breast with increased FDG metabolism, suggestive of breast cancer; bilateral breast hyperplasia; b. Multiple lymph node metastases in the left axilla, left pectoral intermuscular space, left supraclavicular fossa, left posterior cervical triangle, and left deep cervical space; liver metastases; c. Small nodular FDG-enhanced foci in the lateral part of the left breast, suggestive of breast cancer, please correlate with clinical findings.

2. a. Ground-glass nodules in the upper lobes of both lungs and the posterior basal segment of the left lower lobe, with normal FDG metabolism, suggestive of inflammation or atypical adenomatous hyperplasia, CT follow-up recommended; b. Chronic inflammatory nodule in the upper lobe of the right lung, CT follow-up recommended. A few post-inflammatory lesions in both lungs. Reactive hyperplasia of mediastinal lymph nodes.

3. Chronic cholecystitis. Intrauterine device insertion, uterine fibroids are highly likely, please correlate with ultrasound examination.

4. Chronic inflammatory changes or physiological uptake in part of the gastric wall and intestinal tract, please correlate with endoscopy.

5. L4/5 intervertebral disc bulge.

6. Subcutaneous calcifications in the left buttock.

7. Uneven thyroid density with diffusely increased FDG metabolism in the lobes, suggesting possible inflammation; please confirm with ultrasound and laboratory tests.

8. No obvious abnormalities seen on cranial scintigraphy.

9. Chronic inflammation of the left nasopharyngeal wall.

10. Chronic inflammation of both ethmoid sinuses and the left 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.
