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: Normal brain morphology and structure; small patchy low-density lesions with reduced FDG uptake were observed in the left frontal lobe white matter; no abnormal density shadows or FDG uptake were observed in the remaining brain parenchyma.
No widening of the ventricles, sulci, fissures, or cisterns was observed; local density and FDG uptake were normal; and midline structure 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; the sinus walls were intact.
No significant thickening of the soft tissue on both sides of the nasopharynx was observed; the bilateral pharyngeal recesses were symmetrical; and FDG uptake was normal.
The bilateral palatine tonsils showed physiological FDG uptake.
The laryngopharynx showed normal morphology and structure; the parapharyngeal space was clear.
The bilateral parotid and submandibular glands showed normal size, shape, and density; and FDG uptake was physiological.
The thyroid gland was normal in shape and size, with slightly uneven density; and FDG uptake was normal.
Multiple small lymph nodes were observed in the bilateral deep cervical spaces, posterior cervical triangle, submandibular region, and submental region.
The largest was located in the left superior deep cervical space, with a short diameter of approximately 0.7 cm, showing increased FDG uptake (SUVmax = 2.7).
The left lower lobe was reduced in volume, with an irregular, heterogeneous mass of soft tissue density near the hilum, measuring approximately 6.2 5.6 4.0 cm, containing several FDG-high uptake foci (SUVmax = 12.3), and adjacent basal bronchus truncation.
Scattered multiple solid nodules of varying sizes were observed in the lung parenchyma, with clear borders.
The largest was approximately 1.4 cm in long diameter, showing increased FDG uptake (SUVmax = 4.2).
Partial pleural thickening was observed, but no significant pleural effusion was seen bilaterally.
Multiple enlarged lymph nodes were observed in the left hilum, subcarinal region, aortopulmonary window, para-aortic arch, anterior and posterior to the vena cava, right superior tracheoesophageal groove, and left supraclavicular fossa, showing increased FDG uptake (SUVmax = 9.8).
The heart size is normal.
The liver shape and size are normal, with smooth liver margins and no widening of the hepatic fissure.
No abnormal density shadows are seen in the liver parenchyma, and FDG uptake is normal.
No dilation of intrahepatic or extrahepatic bile ducts is observed.
The gallbladder shape and size are normal, with no thickening of the gallbladder wall, no positive stones or obvious masses, and no abnormal FDG uptake in the gallbladder fossa.
The peripancreatic spaces are clear, with no abnormal density shadows in the parenchyma, no widening of the pancreatic duct, and no abnormal FDG uptake.
The spleen shape and size are essentially normal, with no abnormal density or FDG uptake.
The bilateral adrenal glands shape, size, and density are normal, and local FDG uptake is normal.
The bilateral kidneys are normal in shape and size, with no abnormal density shadows in the renal parenchyma, and no significant abnormal FDG uptake.
No widening of the bilateral renal pelvis, calyces, and ureters is observed, and no positive stones are seen locally.
The prostate shape and size are normal, with punctate calcifications seen within, and no focal abnormal increase in FDG uptake is observed.
The bladder is adequately full, with no obvious localized thickening or mass in the wall, and no positive stones were found in the lumen.
The esophagus is not dilated, and the wall is not significantly thickened or swollen; FDG uptake is not increased.
The stomach is well-filled, with slight thickening of the antral wall and increased FDG uptake (SUVmax = 2.7).
The intestines are not sufficiently full, with no localized masses; some intestinal segments show physiological FDG uptake.
No enlarged lymph nodes were found in the abdominal cavity, pelvis, or retroperitoneal region.
Small and enlarged lymph nodes were visible in both inguinal regions, the largest measuring approximately 2.1 0.9 cm; the hilum was visible, and FDG uptake was normal.
No significant fluid accumulation was found in the abdominal cavity or pelvis.
The left inguinal canal is enlarged.
Multiple focal areas of increased FDG uptake (SUVmax = 11.2) were observed in the left scapula, some right ribs, sternum, multiple lumbosacral vertebrae and their appendages, right ilium, right pubis, and left acetabulum, with localized increased bone density.
The spinal sequence shown is normal, with some vertebral body margin osteophytes, and no abnormal uptake was observed in FDG.

Impression

1. a. A mass in the lower lobe of the left lung with significantly increased FDG metabolism, suggestive of left lung cancer with surrounding obstructive inflammation. Multiple metastases in both lungs. Metastases to the left hilar, mediastinal, and left supraclavicular fossa lymph nodes. b. Multiple bone metastases in the right ribs, sternum, spine, and pelvis. c. Possible left frontal lobe brain metastasis; enhanced MRI is required for confirmation.

2. Chronic inflammatory changes in the gastric antrum; endoscopic re-examination is necessary if needed.

3. Prostatic calcifications. Left inguinal hernia. Reactive hyperplasia of bilateral inguinal lymph nodes.

4. Degenerative changes in the spine.

5. Reactive hyperplasia of bilateral cervical 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.
