Whole-body 18F-FDG PET/CT scan in a patient with Lymphoma 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, and resting, a whole-body PET/CT scan was performed.
The whole-body scan showed: multiple lymph nodes in the right deep cervical space, right submandibular region, bilateral posterior cervical triangles, and bilateral supraclavicular fossae; the largest was located in the left supraclavicular fossa, measuring approximately 1.9*1.4cm, with increased FDG uptake (SUVmax=16.1).
Multiple lymph nodes in the bilateral axillae, pectoral intermuscular space, superior mediastinal vascular space, posterior mediastinum, cardiophrenic angle, and anterior diaphragmatic group; the largest was located in the right axilla, measuring approximately 3.3*2.3cm, with increased FDG uptake (SUVmax=20.1).
Multiple lymph nodes in the hepatic hilum, bilateral posterior diaphragmatic crura, retroperitoneal perivascular space, abdominopelvic cavity, bilateral iliac vessels, bilateral pelvic walls, and bilateral inguinal regions; some lymph nodes were fused; the largest was located beside the abdominal aorta, measuring approximately 2.7*2.1cm, with increased FDG uptake (SUVmax=19.3).
The brain morphology and structure are normal.
Multiple soft tissue masses are present in the right frontal lobe, left temporal lobe, and right cerebellar hemisphere.
The largest mass, located in the right frontal lobe, measures approximately 3.6*2.5cm.
FDG uptake is increased, with an SUVmax of 22.5.
Peripheral cerebral parenchymal edema is present.
No widening of the ventricles, sulci, fissures, or cisterns is observed.
Local density and FDG uptake are normal, and midline shift is not observed.
The bilateral eyeballs have normal morphology and outline, and FDG uptake is normal.
No thickening of the paranasal sinus mucosa is observed, and the sinus walls are intact.
No thickening of the nasopharyngeal wall is observed, and FDG uptake is normal.
The pharyngeal recesses are symmetrical bilaterally, and FDG uptake is normal.
The bilateral palatine tonsils are slightly full in shape, and FDG uptake is normal.
The laryngopharynx has normal morphology and structure, and the parapharyngeal space is clear.
The bilateral submandibular and parotid glands have normal size, shape, and density, and FDG uptake is physiological.
The thyroid gland shows uneven density with several low-density nodules in both lobes, the largest being approximately 1.3 cm in diameter, showing increased FDG uptake (SUVmax = 27.4).
The chest is symmetrical, with a small solid nodule approximately 0.3 cm in diameter in the lateral basal segment of the right lower lobe; no abnormal FDG uptake was observed.
A few air-filled cavities are present in the subpleural region of both upper lobes, along with a few linear lesions in both lungs; no abnormal FDG uptake was observed.
No pleural thickening or pleural effusion was observed bilaterally; no abnormal FDG uptake was observed.
The trachea is midline, and the trachea and segmental bronchi are patent, with no significant wall thickening or luminal narrowing.
The heart is within the normal size range, with a lower cardiac chamber density than the myocardium.
No pericardial thickening or effusion was observed.
Some arteriosclerosis is present.
The liver is normal in shape and size, with smooth borders, no widening of the hepatic fissure, and no abnormal density shadows within the liver; no abnormal FDG uptake was observed.
The hilar region is clearly defined.
No dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no obvious abnormalities, but increased density within the gallbladder and a clear gallbladder fossa.
FDG uptake was normal.
The pancreas had a clear outline, normal shape and size, no obvious abnormal density shadows, clear surrounding spaces, no widening of the pancreatic duct, and no abnormal FDG uptake.
The spleen was generally normal in shape and size, with no abnormal density or FDG uptake.
Both kidneys were normal in shape and size, with no localized protrusions at the renal borders and no abnormal density shadows.
The renal pelvis, calyces, and ureters were not widened, and FDG uptake was normal.
The perirenal spaces were clear, and the adrenal glands were normal in shape, size, and density, with no abnormal local FDG uptake.
The esophagus was not dilated, and local FDG uptake in the esophageal wall was not increased.
The stomach was poorly filled, with slight thickening of part of the stomach wall and slightly increased FDG uptake (SUVmax = 2.4).
The intestines were poorly filled, with no local masses, but continuous FDG uptake in part of the intestine (SUVmax = 3.6).
The prostate gland appeared normal in shape and size, and FDG uptake was normal.
A small amount of fluid was observed in the tunica vaginalis of the right testis.
The bladder appeared normal, with no positive stones or obvious masses in the affected area.
Multiple nodules and patches of soft tissue density shadows were observed in the subcutaneous tissue, muscles, and intermuscular spaces throughout the body.
The largest was located in the subcutaneous tissue of the midline abdominal wall, measuring approximately 2.8*1.6cm, with increased FDG uptake (SUVmax = 20.0).
The spinal alignment was normal, with mild osteophyte formation at the margins of some vertebral bodies and facet joints.
A herniated disc was observed between L3 and S1, but FDG uptake was normal.

Impression

1. a. Multiple enlarged lymph nodes throughout the body with increased FDG metabolism (see description for details); b. Multiple nodules and patchy soft tissue density shadows in the subcutaneous tissue, muscles, and intermuscular spaces throughout the body with increased FDG metabolism; c. Multiple low-density nodules in the thyroid gland with increased FDG metabolism; d. Multiple intracranial lesions with increased FDG metabolism; The above suggest malignancy, with a high probability of multi-systemic lymphoma. Please confirm with clinicopathological examination.

2. Chronic inflammatory micronodules in the lower lobe of the right lung. Emphysema in the upper lobes of both lungs, and a few post-inflammatory lesions in both lungs. Anemia. Partial arteriosclerosis.

3. Chronic inflammatory changes in part of the gastric wall and intestinal tract; please follow up with endoscopy.

4. Concentrated bile in the gallbladder. Small amount of hydrocele in the tunica vaginalis of the right testis.

5. Mild osteophyte formation in the spine, and L3-S1 intervertebral disc herniation.

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.
