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 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.
No thickening of the paranasal sinus mucosa was observed; the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; no abnormalities in FDG uptake were observed; 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 in FDG uptake were observed.
The palatine tonsils showed physiological uptake bilaterally.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
Increased FDG metabolism was observed in the right mandibular alveolar region, with SUVmax = 5.0.
The thyroid gland was normal in morphology and size, with slightly uneven density; no abnormalities in FDG uptake were observed.
Several small lymph nodes were observed in the bilateral deep cervical spaces and submandibular region, with normal FDG metabolism.
A solid nodule with spiculated and lobulated margins was seen in the posterior segment of the left upper lobe, proximal to which a subsegmental bronchus of the left upper lobe was truncated.
The lesion measured approximately 1.6*1.3cm, with increased FDG metabolism (SUVmax = 9.2).
Several small solid nodules with clear borders, approximately 0.3-0.6cm in long diameter, were seen in the pleura of the left upper lobe and right oblique fissure, with normal FDG metabolism.
Scattered cystic lucent shadows and linear shadows were observed in the upper lobes of both lungs, with no pleural effusion or pneumothorax bilaterally.
A lymph node was visualized in the left upper hilum, approximately 0.9cm in short diameter, with increased FDG metabolism (SUVmax = 8.0).
A small nodule was observed in the thymic region of the anterior mediastinum, approximately 6mm in long diameter, with no abnormal FDG uptake.
Multiple lymph nodes were observed in both axillae, pretracheal space, para-aortic arch, aortopulmonary window, and below the carina, the largest measuring approximately 0.7 cm in short diameter.
Some showed mildly increased FDG metabolism, with an SUVmax of 3.0.
The cardiac silhouette was normal.
Calcification was observed in some arterial walls (including the coronary arteries).
The esophagus showed no dilation, wall thickening, or masses, and no increased FDG uptake.
Scattered calcifications were present in the left breast, the largest measuring approximately 0.3 cm in diameter.
The right breast showed no significant abnormalities, and FDG metabolism was normal.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
Plain CT scan revealed scattered cystic lesions in the right lobe of the liver, the largest measuring approximately 1.3 x 0.7 cm, with no abnormal FDG uptake.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape or size, with no thickening of the gallbladder wall, increased density within the gallbladder, and no abnormal local FDG uptake.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormalities in FDG uptake.
The spleen is normal in shape, size, density, and FDG uptake.
The right kidney is enlarged, with a slightly high-density, uneven shadow measuring approximately 4.1*2.2cm under the posterior capsule.
The lesion is crescent-shaped in the sagittal plane, with physiological FDG uptake at the lesion's periphery and absent FDG uptake within.
Another low-density lesion of approximately 0.3cm in long diameter is seen in the right kidney, with a CT value of approximately -22 HU; FDG uptake is not increased.
The left kidney is normal in shape and size, with no obvious abnormal density shadows in the parenchyma, no widening of the renal pelvis, calyces, or ureter, and no obvious abnormalities in FDG uptake.
Bilateral adrenal gland imaging is normal.
The stomach is poorly distended, with no obvious thickening of the gastric wall and no obvious abnormalities in FDG uptake.
The intestines are poorly distended, with linear high-density shadows in parts of the intestinal wall; FDG uptake is physiological.
The uterine wall is slightly bulging, and FDG uptake is not abnormally increased.
No abnormal FDG metabolism is observed in the bilateral adnexa.
The bladder is generally full, and no obvious positive stones are seen within it.
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.
Multiple subcutaneous calcifications are present in the left buttock.
The spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies, and L4/5 and L5/S1 intervertebral disc bulges.
There is localized cortical discontinuity in the right 6th-10th ribs, with increased FDG metabolism and an SUVmax of 3.1.

Impression

1. a. Solid nodule in the posterior segment of the left upper lobe with increased FDG metabolism, suggestive of peripheral lung cancer. Left upper hilar lymph node metastasis. b. Small solid nodules in the pleura of the left upper lobe and right oblique fissure, without increased FDG metabolism, suggestive of chronic inflammatory nodules; follow-up with CT is recommended. Scattered emphysema, chronic inflammation, and remnants in both upper lobes. c. Possible reactive hyperplasia of mediastinal and bilateral axillary lymph nodes; partial lymph node metastasis at the aortic window needs further investigation; follow-up is recommended. Calcification of some arterial walls (including coronary arteries). d. Small nodule in the anterior mediastinal thymic region, without abnormal FDG uptake, likely a small thymoma; follow-up is recommended.

2. A slightly high-density lesion with uneven distribution under the capsule of the right kidney, appearing crescent-shaped in the sagittal plane. FDG uptake at the lesion's edge is physiological, while FDG metabolism is absent internally. This suggests a possible subcapsular hematoma in the absorption phase, but space-occupying lesion cannot be ruled out. Further diagnosis requires clinical examination and enhanced MRI. Right renal angiomyolipoma.

3. Right lobe hepatic cyst. Cholestasis in the gallbladder. Linear high-density shadows in part of the intestinal wall, suggestive of schistosomiasis.

4. Scattered calcifications in the left breast; follow-up ultrasound is needed.

5. Possible uterine fibroid; follow-up ultrasound is needed.

6. Fractured changes in the right 6th-10th ribs; clinical correlation is needed. Partial vertebral osteophyte formation. L4/5 and L5/S1 intervertebral disc bulge. Multiple subcutaneous calcifications in the left buttock.

7. No obvious abnormalities were found on cranial scintigraphy. Localized inflammatory uptake in the right inferior alveolar ridge.

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.
