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: 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 was observed in the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical and showed no significant abnormalities.
No thickening was observed in the paranasal sinus mucosa, and the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; no abnormalities were observed in FDG uptake; the pharyngeal recesses were symmetrical; there was no narrowing of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the parapharyngeal spaces were clear bilaterally, and no abnormalities were observed in FDG uptake.
The palatine tonsils showed physiological uptake.
The laryngopharynx was normal in morphology and structure.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The thyroid gland was normal in morphology and size, with uniform density; no abnormalities were observed in FDG uptake.
No enlarged lymph nodes were observed bilaterally in the neck; no abnormalities in FDG metabolism were observed.
A small ground-glass nodule with a CT value of approximately -593 HU and a long diameter of approximately 0.4 cm was observed in the anterior segment of the right upper lobe, with relatively clear borders and normal FDG uptake.
Multiple scattered patchy ground-glass opacities were observed in both lower lobes.
A solid nodule with a long diameter of approximately 0.4 cm was observed in the right middle lobe, with normal FDG uptake in both cases.
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.
No esophageal dilation, significant wall thickening, or mass was observed, and FDG uptake was not increased.
The cardiac chamber density was lower than that of the myocardium.
The right breast was dense with heterogeneous density; a dense soft tissue nodule measuring approximately 2.7 3.5 cm was observed in the upper inner quadrant, with increased FDG uptake (SUVmax = 3.2).
The left breast was normal, with normal FDG uptake.
Small lymph nodes, approximately 0.4 cm in short diameter, were observed in both axillae.
FDG metabolism was normal.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissures.
Plain CT scan showed no significant abnormal density shadows in the liver parenchyma, and FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape or size, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no significant abnormal FDG uptake.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size, with no significant abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters were not widened, and FDG uptake was normal.
Bilateral adrenal glands showed no significant abnormalities on contrast.
The stomach was poorly distended, with no significant thickening of the stomach wall and no significant abnormal FDG uptake.
The intestines are poorly filled, with no obvious thickening or mass in the intestinal wall; FDG uptake is physiological.
The uterus is full and irregularly shaped; FDG metabolism is normal.
A solid mass measuring approximately 5.2 3.5 cm is seen in the right adnexal region; FDG metabolism is increased, SUVmax = 3.4.
A similar lesion with a long axis of approximately 3.0 cm is seen in the left adnexal region.
A nodule with increased FDG metabolism, approximately 1.4 cm in long axis and SUVmax = 2.6, is seen in the rectouterine pouch peritoneum.
Abdominal and pelvic effusions are present.
Bilateral paracolic gutter shadows are present; FDG uptake is normal.
The bladder is generally full, with no obvious positive stones.
No enlarged lymph nodes are seen in the abdominal cavity, pelvis, or retroperitoneum; FDG metabolism is normal.
The spinal alignment is normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulges; FDG uptake is normal.
Uneven bone density was observed in the spine and pelvic bones, but no significant abnormalities were found in FDG metabolism.

Impression

1. Right breast mass with increased FDG metabolism, consistent with breast cancer based on pathology. Reactive hyperplasia of small lymph nodes in both axillae.

2. a. Bilateral adnexal masses with increased FDG metabolism, suggestive of malignancy, possible metastasis, ovarian cancer to be ruled out; comprehensive analysis with contrast-enhanced MRI is recommended. b. Peritoneal metastasis in the rectouterine pouch. Uterine fibroids. Abdominal and pelvic effusion. c. Bilateral paracolic gutter opacities, no significant abnormalities in FDG uptake; follow-up recommended. d. Heterogeneous bone density in the spine and pelvis, no significant abnormalities in FDG metabolism; follow-up recommended.

3. Ground-glass nodule in the anterior segment of the right upper lobe, no abnormalities in FDG metabolism; suggestive of inflammatory nodule or atypical adenomatous hyperplasia; annual HRCT follow-up recommended. Scattered chronic inflammation in both lower lobes of the lungs. Chronic inflammatory nodule (solid) in the right middle lobe. Anemia.

4. Cervical, thoracic, and lumbar vertebrae osteophyte formation. L4/5 and L5/S1 intervertebral disc bulges.

5. No abnormalities were found on cranial imaging.

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.
