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: small patchy low-density lesions with decreased or absent FDG uptake in the white matter of the right frontal and parietal lobes.
A solid nodule, approximately 0.8 cm in diameter, was seen in the cerebellar vermis, with increased FDG uptake (SUVmax = 8.5), surrounded by patchy low-density lesions with decreased FDG uptake.
No widening of the ventricles, sulci, fissures, or cisterns was observed; local density and FDG uptake were normal, and midline shift was not observed.
The bilateral eyeballs showed normal morphology and outline; retrobulbar structures were clear, and FDG uptake was normal.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No significant thickening of the soft tissue on both sides of the nasopharyngeal walls was observed; the bilateral pharyngeal recesses were symmetrical, and FDG uptake was normal.
The bilateral palatine tonsils were full, and FDG uptake was physiological.
The laryngopharynx showed normal morphology and structure, and the parapharyngeal spaces were clear.
The size, shape, and density of both parotid and submandibular glands were normal, and FDG uptake was physiological.
The thyroid gland was normal in shape and size, with uneven density, and FDG uptake was normal.
Small lymph nodes in the bilateral deep cervical spaces, submandibular region, and posterior cervical triangle were visible, and FDG uptake was normal.
An irregular soft tissue nodule was seen in the lower lingular segment of the left upper lobe, with clear borders, measuring approximately 1.61.71.4cm, containing a few punctate calcifications, and long spiculated shadows at the edges; FDG uptake was increased, SUVmax=2.1.
Two solid small nodules were seen in the right middle lobe, with clear borders; the larger one had a long diameter of approximately 0.4cm, and FDG uptake was normal.
A few flocculent ground-glass opacities were seen in the subpleural region of both lower lobes, and FDG uptake was normal.
No significant pleural thickening or pleural effusion was observed bilaterally.
Multiple enlarged lymph nodes were observed in the left hilum, pretracheal vena cava, aortic window, anterior mediastinum, superior mediastinal vascular space, and bilateral supraclavicular fossae.
The lymph nodes had indistinct margins, with the largest located in the left supraclavicular fossa, measuring approximately 1.7 cm in short diameter.
FDG uptake was increased, with an SUVmax of 8.6.
No enlarged lymph nodes were seen in the right hilum, and FDG uptake was not significantly increased.
The heart size was normal.
Both breasts showed dense fibrous glands.
A suspicious nodule with a long diameter of approximately 1.4 cm was observed in the central region of the left breast, with relatively increased FDG uptake (SUVmax = 3.2).
Small lymph nodes were visible in both axillae, with normal FDG uptake.
The liver morphology and size were normal, with smooth borders and no widening of the hepatic fissure.
The liver parenchyma showed decreased density, with an average CT value of approximately 46 HU.
A small, round, low-density lesion with a diameter of approximately 0.3 cm was seen at the top of the hepatic diaphragm, with normal FDG uptake.
No dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder is normal in shape and size, with no thickening of the gallbladder wall, no contrast agent retention within the lumen, and no abnormal FDG uptake in the gallbladder fossa.
The peripancreatic spaces are clear, with no obvious abnormal density shadows in the parenchyma, no widening of the pancreatic duct, and no abnormal FDG uptake.
The spleen is generally normal in shape and size, with no abnormal density or FDG uptake.
The bilateral adrenal glands are normal in shape, size, and density, with no abnormal local FDG uptake.
The bilateral kidneys are normal in shape and size, with no obvious abnormal density shadows in the renal parenchyma, and no obvious abnormal FDG uptake.
The renal pelvis, calyces, and ureters are not widened, and no positive stones are seen locally.
The bladder is adequately filled, with no obvious localized thickening or mass in the wall, and no positive stones are seen within the lumen.
The uterus is normal in shape and size, with decreased density in the uterine cavity and increased FDG uptake (SUVmax = 3.4).
An oval-shaped low-density lesion with a long diameter of approximately 1.3 cm is seen in the cervical region, with no abnormal FDG uptake.
A cystic low-density lesion measuring approximately 3.1 2.6 cm with clear borders and absent FDG uptake was observed in the left adnexal region.
No esophageal dilatation, wall thickening, or mass was observed; FDG uptake was not increased.
The stomach was well-displaced, with slight thickening of the antral wall and increased FDG uptake (SUVmax = 3.1).
Intestinal displacement was unsatisfactory; no local mass was observed, but FDG uptake was increased in some intestinal segments (SUVmax = 6.2).
Small retroperitoneal lymph nodes were visible, with no increased FDG uptake.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment was unstable, with osteophyte formation at the margins of some vertebral bodies, slight anterior displacement of the L5 vertebral body with pars interarticularis fracture, and L1/2 disc herniation with calcification; FDG uptake was not abnormal.

Impression

1. a. Irregular soft tissue nodules in the lower lingular segment of the left upper lobe with mildly increased FDG metabolism, suggestive of lung cancer, but chronic inflammatory lesions need to be ruled out. A biopsy is recommended for definitive diagnosis. b. Multiple enlarged lymph nodes in the left hilum, mediastinum, and bilateral supraclavicular fossae with increased FDG uptake, highly suggestive of metastatic tumors. c. Multiple lesions in the right cerebral hemisphere and cerebellar vermis, highly suggestive of metastatic tumors.

2. a. Chronic inflammatory solid nodules in the right middle lobe. Bilateral lower lobe aspiration effect. b. Bilateral dense glandular tissue, suspicious nodule in the central region of the left breast with mildly increased FDG metabolism, suggestive of fibroadenoma; ultrasound examination is recommended. Bilateral axillary lymph node reactive hyperplasia.

3. Uterine cavity physiological uptake is highly likely, Nabothian cysts of the cervix, cystic lesions in the left ovary; follow-up ultrasound is recommended. Reactive hyperplasia of small retroperitoneal lymph nodes.

4. Gastric antrum contraction with physiological uptake or chronic inflammatory changes; endoscopic re-examination may be necessary. Physiological uptake of some intestinal segments. Fatty liver, small hepatic cysts.

5. Degenerative changes in the spine, L5 vertebral body grade I anterior slippage with pars interarticularis fracture, L1/2 intervertebral disc herniation with calcification.

6. Reactive hyperplasia of bilateral cervical small lymph nodes.

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.
